ABSTRACT:
A circulating current control for a phase shifted full bridge inverter is provided to control the powder dissipation and efficiency of the converter responsive to changing operating conditions. The minimum circulating current necessary for zero-voltage switching is regulated by adjusting the reset current of saturable reactors. Therefore, zero-voltage switching can be achieved with a minimum of condition losses. The converters efficiency is optimized over a wide range of operating conditions.
