摘　　要：针对设计的电源要求有很强的带不平衡负载能力,提出一种组合式400 Hz中频电源的设计方案,其优点在于在三相不平衡负载的情况下,能保持三相电压的平衡。给出主电路及控制电路设计,分析基于DSP的同步信号的接收和发送的处理以及正弦脉宽调制的实现。仿真及试验结果验证了该方案的可行性。This article describes the DSP-based control of three-phase power system frequency 400 Hz,compare with the traditional medium frequency power supply,new design has a strong imbalance in the load capacity to meet the needs of customer. The main circuit and control circuit are described in detail. Synchronization between three module is realized by DSP, as well as SPWM. Finally, experimental results are given.

关 键 词：中频电源 不平衡负载 DSP 正弦脉宽调制
