ABSTRACT:
A circuit is provided to reduce power loss on switching. A pair of auxiliary switching devices is switched on before a pair of switching devices. The switching devices are switched on after a corresponding capacitor to the auxiliary switching devices is discharged to zero. Thus, the power loss of the switching devices is reduced.
