Abstract: Fivephase fullbridge rectifier circuit was analysed for fivephase generator of regulator system. The simulation models on threephase and five phase full bridge control rectifier circuit were established based on Matlab/Simulink system. Through on resistance sexual load of work characteristics simulation was analysed, compared to threephase rectifier circuit, the pulse frequency of fivephase rectifier circuit output voltage is higher, output ripple is smaller, ripple factor is lower, and the average of output voltage is higher. Fivephase rectification circuit applied to vehicle power system can improve the quality of power supply to meet the needs of vehicle electrical appliances.
