It seems to me that flyback SMPSes use pulsed DC instead of AC. Is this
true?
For example, here, the transistor simply turns on and off, providing
pulses to the transformer, right?
http://www.repairfaq.org/sam/smpsbd.gif
Would SMPSes be more efficient if their transformers were fed
high-frequency AC instead of high-frequency pulsed DC (for example, by
using an H-bridge to provide a negative voltage across the transformer
primary for the second half of each cycle)?

Your flyback is using the impulsing current.
But the term "impulsing current" was used by Tesla.
Up to now the Tesla name is absent in textbooks about radio.
Do You know that Tesla was "Father of radio":

See at the Fig. 1 and Fig. 2:
http://www.nobelprize.org/nobel_prizes/physics/laureates/1909/braun-lecture.pdf
On the Fig. 1 is the Hertz transmitter.
On the Fig. 2 is the Tesla transmitter.
Do you see the difference?
It is described here: "
"At about that time there was a significant problem of interference between
signals coming from different sources, due to the increasing number of
transmitting stations. Guglielmo Marconi was the first to adopt a tuning
system of this type. It's essentially composed of a tesla type high
frequency transformer, whose primary circuit is connected to a leyden jar,
forming a resonant circuit which reduces the bandwidth of the signal to be
transmitted coming from an induction coil. The signal then goes to the
central coil (secondary circuit) whose terminals are connected to the
transmitting aerial the earth circuit, to be sent into the space. " From:
http://www.sparkmuseum.com/SPKTRAN.HTM
The radio "It's essentially composed of a tesla type high frequency
transformer".
For this reason Tesla is "The Father of radio".

Such a text as you cited above is no proof for Tesla's priority.
There is a world outside the US, even when Americans don't know about.
Americans are tought that TESLA invented everything,
in defense of the US Tesla patents and revenues. Money, in short.
I even doubt that Marconi was the first to use "tuning circuits".
Too obvious is the pathway, to believe only one person found it.

Tesla had published everything about his discoveries.
The most important is that from 1892 (Marconi was 15 years old):
http://www.tfcbooks.com/tesla/1892-12-21.htm
"The apparatus, oscillator and resonator, being immersed in air, or other
discontinuous medium, there occurs-as I have pointed out in the description
of my recent experiments before the English and French scientific
societies-dissipation of energy by what I think might be appropriately
called electric sound waves or sound-waves of electrified air. "
The "Coils and resonance circuits" produce the very high voltage. Such is
necessary to long distance comunication.
Hertz made the "near field comunnication" (proximity card).
Popow and young Marconi were using too low voltage.
Marconi means the factory and the owner of the factory. The Marconi were
using the Tesla patents.
The electric waves were discovered by Henry in 1841.
They were discovered again in 1871 by E. Thomson and proved by Prof. Houston
in 1975.
The device for extra strong electric waves was invented by Tesla in 1891.
But the Nobel price for electric waves was given to Braun and Marconi.
The long distance comunication was very important for ships. The rest were
using the telegraff and telephone.
So Father of radio is Tesla.
