Description: This paper proposes a new design procedure for a bidirectional LCL DC-DC converter. This converter employs two DC/AC insulated-gate bipolar transistor-based (IGBT) converters and a passive LCL filter instead of a typical high frequency transformer. The presented LCL filter design is based on zero reactive power. Higher step ratio is achieved by utilizing post-resonant mode of operation. The proposed converter has very low losses, particularly under rated load, and can easily tolerate DC faults. The design is tested via EMTP-RV digital simulation for a 20-MW 24kV/1.2kV converter and experimentally validated on a 200-W 100V/20V prototype converter.
