Peak Load Voltage and DC Circuits

[Joe]

I am trying to understand the concept of Peak Load Voltage and how it
applies to DC circuits. If the circuit is DC rectified, how can there
be peak voltages? I thought the DC circuit would be smooth. Thanks for
your help.

A common meaning of DC is unidirectional, without respect to
magnitude. So a time varying voltage that never reverses polarity is
within the definition of DC. Of course another way of looking at such
a voltage is that it is an addition of a smooth DC and various AC
components (that are not large enough to add up to enough magnitude to
ever completely cancel the DC and reverse the polarity of the sum).
