摘　　要：提出了一种用于燃料电池电动汽车的基于DSP的多路并联DC/DC(直流/直流)变换器解决方案。以双路为例给出了相差180°相位的PWM实现方法。并且在小功率电路上进行了试验,达到了预期的效果。A new solution of multiphase shunt-wound DC/DC converter based on DSP for fuel cell electrical vehicle （FCEY） was presented. Taking dual-circuit DC/DC converter as example, the implementation of the puls width modulation with phase difference of 180° was achieved. At last, a low-power test was accomplished and the expected effect was obtained.
