In one embodiment, a power converter system includes a first input
terminal and a second input terminal operable to connect to an
alternating current (AC) power source, and an output terminal at which an
output voltage can be provided to a load. A first inductor and a first
diode are connected in series between the first input terminal and the
output terminal. A second inductor and a second diode are connected in
series between the second input terminal and the output terminal. A first
switch is connected to the first inductor and the first diode, and a
second switch is connected to the second inductor and the second diode.
The first switch and the second switch alternately function as a boost
switch and a synchronous rectifier for charging and discharging the first
and second inductors during operation of the power converter system. An
auxiliary network is operable to provide for zero voltage switching (ZVS)
and zero current switching (ZCS) conditions for both the first and second
switches during operation of the power converter system.
