The weight, volume, and cost of power electronic converter will be significantly decreased by the use of silicon carbide device, which will also enormously increase the performance of power electronic system. A design of high frequency and efficiency marine frequency converter based on silicon carbide device is presented in this paper. The frequency converter system structure is based on the voltage-source dual PWM AC/DC/AC topology, in which the rectifier part and the inverter part make use of the latest generation silicon carbide device. Active front-end frequency converter structure, control system strategy of the rectifier and the inverter, and parameters calculation method of the main circuit are included. The system simulation and experimental results show that it is an effective technological approach to implementation of marine frequency converter with high performance and miniaturization.
