The invention discloses a V2G power supply system based on a silicon carbide field effect transistor. The V2G power supply system comprises an AC power supply end, a DC power supply end, an AC/DC circuit, a first filter circuit, a DC/DC circuit, an LLC resonance circuit, a second filter circuit, an AC/DC driving circuit, a DC/DC driving circuit, an LLC driving circuit, an AC/DC signal sampling circuit, a DC/DC signal sampling circuit, an LLC signal sampling circuit and a digital signal processor circuit. Compared with a power supply system adopting a traditional power device, the power supply system has the advantages of smaller size, higher power density, higher switch working frequency and stronger high-temperature-resistant adaptive capacity of system working.

    本发明公开一种基于碳化硅场效应管的V2G电源系统,包括交流电源端和直流电源端、AC/DC电路、第一滤波电路、DC/DC电路、LLC谐振电路、第二滤波电路、AC/DC驱动电路、DC/DC驱动电路、LLC驱动电路、AC/DC信号采样电路、DC/DC信号采样电路、LLC信号采样电路和数字信号处理器电路;相较采用传统功率器件的电源系统,具有更小的体积、更高的功率密度,更高的开关工作频率,系统工作的耐高温适应能力更强。
