For the rectifier part it was again the class E topology that
were chosen, this time due to the forward voltage drop of the
diodes. With a low-voltage output, the forward voltage drop of
the diode becomes a significant percentage of the output voltage
and a single diode rectifier was found to be the best choice. For
higher output voltages, theDErectifier might be better as the loss
due to forward voltage drop in the diodes becomes insignificant
and the voltages stress of the devices the major concern.
Three different power stages were made; one with a MOSFET
with the lowest available output capacitance, one with
