An input filter is usually employed between a dc-dc
converter and its unregulated power source.
The filter serves to prevent the converter switching current ripples being
reflected back into the source and also to isolate source voltage

Power conditioners for low-voltage DC sources in
Distributed Generation usually have two major functions: to
boost the energy source output voltage and to convert it into an
AC voltage. The voltage boost is usually done by a DC-DC
converter.

This paper introduces a new dc-dc converter suitable
for operation at very high frequencies under on-off control. The
converter power stage is based on a resonant inverter (the 2
inverter) providing low switch voltage stress and fast settling
