AC-AC CONVERTER

The present invention relates to a AC-AC converter, which has particular relevance to a converter for an inductive or capacitive (wireless) power transfer system. More specifically, the current invention discloses an AC-AC converter comprising a bridge circuit having a first leg and a second leg, each leg including a high switch and a low switch, the high switches being connected to a first energy source and the low switches being connected to ground, a coupling network(s) having a first connection between the switches of the first leg and a second connection between the switches of the second leg, a second (or multiple secondary) energy source(s) connected between the coupling network(s) and ground.
