Abstract: A resonant circuit includes first, second, and third input nodes configured to receive a three phase input power and is formed as a delta circuit including a first leg connected between a first corner node and a second corner node, a second leg connected between the second corner node and a third corner node, and a third leg connected between the third corner node and the first corner node. A first outer resonant device is connected between the first input node and the first corner node, a second outer resonant device connected between the second input node and the second corner node, and a third outer resonant device connected between the third input node and the third corner node. Each leg of the delta circuit includes an inner resonant device connected in series with a corresponding transformer.
