  • Converter
    Patent number: 11451091
    Abstract: A converter including 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, and a second (or multiple secondary) energy source(s) connected between the coupling network(s) and ground, wherein the coupling network comprises a first inductive element connected between the second energy source and the switches of the first leg, and a second inductive element connected between the second energy source and the switches of the second leg.
