Abstract
This paper proposes a soft-switching cell, based on the concept of input voltage cancellation or switching input supply, performed with a resonant commutated pole at the input of any bridge converter. The proposed auxiliary switching cell permits soft switching in all bridge topologies (half bridge, full bridge and 3-phase), in any load conditions, even with bi-directional input current
