Design of a high power low losses DC-DC converter for mining applications
This paper proposes a new design procedure for a bidirectional LCL converter which has a potential to be applied in mobile mine equipment. This type of a converter employs two DC/AC insulated-gate bipolar transistor-based (IGBT) converters and a passive LCL filter instead of a traditional high frequency transformer. LCL filter design is based on both zero reactive power circulation and minimization of voltage across the capacitor. Switching losses are minimized by using soft switching operation. Lower capacitor voltage and related lower stepping ratio can be mitigated by choosing an appropriate switching frequency. The designed converter has attractive performance characteristics under DC faults. The design process and converter performance evaluation are carried out using EMTP-RV digital simulation for a 20-MW 24kV/1.2kV converter. The proposed converter design is experimentally validated by developing a 200-W 100V/20V prototype converter.
