Study of a Novel Three-phase Emergency Power Supply Circuit

LI Ming-yue,QIAN Zhao-ming,YU Xian-feng,PENG Fang-zheng(Zhejiang University,Hangzhou 310027,China)  
A novel circuit of three-phase Emergency Power Supply(EPS) is introduced in this paper.The bidirectional DC/DC converter is used to charge and discharge battery,bidirectional PWM converter is used as rectifier and inverter,Digital Signal Processor(DSP) is used to control the main circuit of the EPS.Through the analysis on principles,simulation and experiment showed that this circuit is feasible.
