Class E isolated dc-dc converters regulating the output voltage at
fixed switching frequency is presented and experimented. It
consists of class E series resonant inverter, high-frequency
transformer and the controllable class E low dv/dt synchronous
rectifier. By controlling the conduction time of a controlled
switch in rectifier, high-frequency ac current will be rectified
and the output voltage can be controlled or regulated in same
time. By parallel connecting the rectifiers at each secondary coils
of transformer and apply the PWM control to each rectifier, it
can supplies and regulates the multiple output voltages at a fixed
switching frequency and maintains the ZVS condition of all
switches from full-load to open-load.
