Abstract
A switching current converter is connected in parallel with each controlled power switch in an electric circuit so that it is allowed to operate from the input voltage and transfer energy from input to output during the turn-on periods of the controlled power switch, whereby each power switch is allowed to be turned ON when a near-to-zero voltage is present across it. The switching converter serves as an active power switch stress relieving means, resulting in minimizing the switching loss in the power switch while providing the energy for operation of the power switch in a very efficient way.
