The purpose of this study is to develop power circuits for AC electric trains with weight reduction and downsizing. We devised a new power circuit configuration which uses SiC modules for insulation function instead of the main transformers, manufactured the circuit models on an experimental basis, and executed the verification. The results verified the bidirectional operation, demonstrating that about a 5.7kW of power was transmitted for the input voltage of up to 200V and the switching frequency of 20kHz run, while ensuring the insulation state without any simultaneous conduction between the primary and secondary terminals through the flying capacitor.
