摘　　要：基于全桥式电路的直流偏磁、电弧加工过程中的电流冲击及长时间高速粗加工过程中逆变电源的温升等问题 ,通过对实际数据和波形的分析 ,提出了选择合适的工作频率及采用峰值电流和平均电流综合反馈逐波控制方式 。Based on the analysis of actual datum and waveforms which were detected from a full bridge topologic invert generator with regard to magnetic bias current impact and temperature rise, a synthesized average current and peak current control method was adopted. Through the cycle by cycle control mode, any imbalance or current change which occurs in arc machining was corrected by online feed adapting. Combined with the suitable switching frequency, a higher reliability of generator in arc machining was obtained.
