I can't say many things I cook have large solid lumps. All ready meals are pretty much fluid, so convection and conduction can take place, and almost everything I cook is a dish of something which is only 2 inches deep.

I don't know what the low settings are for. All the instructions I've
seen - e.g. on ready meals - say "full power". There is the defrost
setting, but microwaves aren't very good at defrosting as they don't
heat frozen water very well.

Mine thaws a frozen (already cooked) pizza extremely well, on full power. It turns a -20C pizza into a +40C pizza in 4 minutes.

Only a moron would cook a pizza in a microwave.

No, anyone who wants it ready more quickly. I buy the frozen pizza in the supermarket, place it in the microwave, then I can eat it in 4 minutes.

Why would you think pizzas shouldn't go in microwaves?! Every foodstuff can be cooked in a microwave.

Because some of us are more interested in good results than in speed.

When I want pizza, I make the crust from scratch, wait for it to rise,
shape it, top it, and bake it at 550 F.

And your stomach is happy to wait?!

Wrong.

Both styles actually take AC incoming mains, raise it to 5k or so,
and convert it with a single diode mind you, to DC to feed the
magnetron. The filament is fed by low voltage AC. Neither of them can
or do vary the voltage going to the magnetron. That's just not how it
works. You can't lower the voltage to reduce microwave energy. And
you can't raise it to get more microwave energy, either. The
magnetron requires voltage within a certain range to function. More
than that will burn the magnetron up. Less will prevent it from
making viable microwaves.

So what we need is a bigger fucking magnetron. More power! Get one from Binford!

So what is the difference between inverter and non inverter types? Is
'inverter' an appropriate term? How do either control the power?

He abundantly and mostly correctly explained that in his previous post,
including the one you copied. The inverter type still pulse the magnetron,
just at a very fast rate, so that for all practical purposes, it's
like being continuous. It's like dimming a 100W bulb. If you turn it
on and off half the time in 1 second cycle times, you will see it blinking.
If you do that with a very fast cycle time you will see a dimmed but
continuous light. That's how bulb dimmers work too.

Well they're meant to, but you can see them flickering, especially at the lower quarter of brightness. Or maybe I have better eyesight than the designers?

That about covers it. Not sure how useful more power would be.
For example, last night I was thawing out a tomato sauce in a
quart plastic container. The Panasonic has a defrost mode that
uses about 30% power and cycles that.


It gets the 30% power by cycling the 100% power on 30% of the
time.

(By the way, adjusting the level does not actually change the
wattage. It simply means the microwave will pulse on and off at
its fixed wattage until the desired level is reached.)

That was true of the first generation of Microwaves, but the
current
"inverter" driver units actually CAN throttle the power. Inverter
microwaves are much better for defrosting AND cooking.

We've had ours for about 2 years now - replacing our original
that we bought in about 1985.

BIG difference (but the old one would likely still be working by
the time this one dies)

Why is it called an invertor? I thought an invertor was a device
to increase the voltage - like running 240V devices off a 12V car
battery.

It's actually a switching power supply, instead of the old heavy step
up transformer, diode and capacitor system. And contrary to the other
posters reply, there 'inverter' style microwave is NOT throttling the
power going to the magnetron. It's still getting high voltage DC
current, just like the original ones. It's better able to control the
timing period for magnetron on/off cycles as well as independent
control over the magnetrons required filament. the old step up
transformer style fired the element with another tap on the
secondary. so, if the transformer had power, both the filament and
magnetron do too. No way to seperate them in that design.

Why could they not be switched independantly after the stepup transformer?

And why on earth would you not want to cook on full power? I've
never had a reason to lower the power from the maximum of 800W. I
want the meal as soon as possible!

You aren't lowering or raising the power to your magnetron when you
adjust those cooking settings. All you're actually doing is telling
the microwaves computer how long to leave the magnetron on for. Ie:
how fast does it cycle the magnetrons power state. For the old heavy
ones, non 'inverter', it's opening/closing a single pole relay that
controls the input on the primary coil to the step up transformer.
Your 'cooking' settings determine how long that relay stays open and
closes for. That's all. Anytime it's closed, your magnetron (in your
case) is kicking 800watts of microwave energy. You can't adjust that.
What you can adjust is how long it's firing the energy into the
cooking chamber.

Yes I know that. But however it lowers the total cooking power, I've never felt the need to use less than all of it. Just as when I drive a car, I only lift my foot off the floor for a corner or a slow woman driver in front of me.

Which is in fact changing the power input to the magnetron and the power
output of the magnetron. It's like a 100W bulb on a dimmer. I set the
dimmer to 50%, is the dimmer still delivering 100W? Is the bulb still
putting out 100W? No, it's now 50W.

Not really true with the old microwaves where the on/off cycle was every 10 seconds! All that does is make the food hot then warm then hot then warm, not very good I would have thought.

Why do you persist in posting waffle about which you know
absolutely
nothing, twould be better to post on subjects you know or ask and

I know what a fucking invertor is, I built my own solar panel
system.

LMFAO! There it is again. Nobody else brags about you therefore, brag
about yourself when nobody asked. LMFAO! Pathetic wanker.

I wasn't bragging, I was stating I know how inverters work. Why on
earth would you see that as bragging? You have some weird mental
problem.


It's simple....
beginning of sentence> "I know how inverters work." <end of sentence

See that? No requirement of why or bragging about an accomplishment. I
simply stated I know how they work. If required, you could explain the
process of the inverter without stating you built something. But not
you.... you do man! LMFAO!

I know, we all have weird mental problems because you say so. You're
the
best!

I backed up my reasoning as yo why I know how they work. Why you see
that as bragging, nobody knows.


LMFAO! Pathetic wanker.

You're not very good at comprehending English are you? I have built a
solar power system using invertors by myself. Therefore I know what an
invertor is and how it works. That is a statement of fact, not bragging.

LMFAO! Pathetic wanker.

You have the same little intelligence as Rod Speed and Steve Pounder. Try responding with a sentence instead of an insult I'd see from a 6 year old.
Not sure why I'm trying to have a discussion about something technical with a woman anyway.

I bought a small apple tart at a stall at Manchester Airport the other day and the assistant said she was going to put it in the oven for 3 seconds. I asked how powerful the oven was and she said 1,900 watts. My tart was certainly warm - I didn't observe exactly how long she gave it!

Exactly, more power, less time.

Which is why when DEFROSTING something that's in a plastic container you
use the DEFROST cycle that uses low power and then cycles even that after
about 75 secs.

I'm not talking about defrosting. I've bought ready meals which are sat at room or fridge temperature, they go in the microwave to heat and the plastic melts.

You've said you just use yours for cooking pre-made
frozen dinners and the like, which is crap I wouldn't even eat.

It's more tasty and quicker to make :)

Others here use microwaves for other uses, including defrosting raw foods that
you don't want to cook in the microwave. I gave you an example, pork chops.
I want them DEFROSTED, not cooked. Once DEFROSTED, I can then brine them,
marinate them, grill them, so what I would with any fresh pork chops.

What a palava. We invented ready meals for a reason.

Or defrosting tomato sauce that in a plastic container. I want the sauce
DEFROSTED, not a melted container. I suppose I should only freeze foods
in ceramic bowls that go in a microwave?

You take them out of the container they were in dumbass.

You can't get most frozen food, like sauce, out of a one quart plastic container until
it's at least partially defrosted moron. You wouldn't even know, because
you apparently don't prepare and then freeze food in those kinds of containers.

I don't freeze things in stupid containers, no.

You're living off pre-cooked, TV dinner crap. Anyone that makes a post
saying there is no reason not to cook pizza in a microwave has already
said way more than enough about their knowledge of food and cooking.

You carry on wasting your time if you like, I have hobbies and other things I prefer to do than fucking about making food. Food is a fuel, if it tastes nice and gives me energy, that's fine, then I can get on with my life.

Higher powered microwaves would require higher powered
electric outlets, probably 220VAC (in the USA).

Also it is questionable whether higher powered ovens would be
practical for use. Getting warming times down to a couple of
seconds might not be a good idea. More speed is not always
better.

That about covers it. Not sure how useful more power would be.
For example, last night I was thawing out a tomato sauce in a
quart plastic container. The Panasonic has a defrost mode that
uses about 30% power and cycles that.


It gets the 30% power by cycling the 100% power on 30% of the
time.

(By the way, adjusting the level does not actually change the
wattage. It simply means the microwave will pulse on and off at
its fixed wattage until the desired level is reached.)

https://lifehacker.com/5974788/familiarize-yourself-with-your-mic
rowaves-power-settings-to-make-microwave-cooking-a-joy
That was true of the first generation of Microwaves, but the
current
"inverter" driver units actually CAN throttle the power. Inverter
microwaves are much better for defrosting AND cooking.

We've had ours for about 2 years now - replacing our original
that we bought in about 1985.

BIG difference (but the old one would likely still be working by
the time this one dies)

Why is it called an invertor? I thought an invertor was a device
to increase the voltage - like running 240V devices off a 12V car
battery.

It's actually a switching power supply, instead of the old heavy step
up transformer, diode and capacitor system. And contrary to the other
posters reply, there 'inverter' style microwave is NOT throttling the
power going to the magnetron. It's still getting high voltage DC
current, just like the original ones. It's better able to control the
timing period for magnetron on/off cycles as well as independent
control over the magnetrons required filament. the old step up
transformer style fired the element with another tap on the
secondary. so, if the transformer had power, both the filament and
magnetron do too. No way to seperate them in that design.

And why on earth would you not want to cook on full power? I've
never had a reason to lower the power from the maximum of 800W. I
want the meal as soon as possible!

You aren't lowering or raising the power to your magnetron when you
adjust those cooking settings. All you're actually doing is telling
the microwaves computer how long to leave the magnetron on for. Ie:
how fast does it cycle the magnetrons power state. For the old heavy
ones, non 'inverter', it's opening/closing a single pole relay that
controls the input on the primary coil to the step up transformer.
Your 'cooking' settings determine how long that relay stays open and
closes for. That's all. Anytime it's closed, your magnetron (in your
case) is kicking 800watts of microwave energy. You can't adjust that.
What you can adjust is how long it's firing the energy into the
cooking chamber.

Which is in fact changing the power input to the magnetron and the power
output of the magnetron. It's like a 100W bulb on a dimmer. I set the
dimmer to 50%, is the dimmer still delivering 100W? Is the bulb still
putting out 100W? No, it's now 50W.

Not really true with the old microwaves where the on/off cycle was every
10 seconds! All that does is make the food hot then warm then hot then
warm, not very good I would have thought.

Yes, you actually are that pig ignorant.

It allows more time for the heat to move from the
outer layer of a big chunk of stuff like with a leg
of lamb or quart of something you are defrosting
to the inside where the microwaves don't get to.
