【摘要】 本文对传统的逆变电源自激起动过程进行了详细的分析，指出了改善逆变电源起动过程的途径，并介绍了一种笔者研制的采用单片机和有自关断能力的大功率晶体管ＧＴＲ（或可关断可控硅ＧＴＯ）构成的逆变电源电路．由于该电路中触发信号与负载不相关，因而大大地改善了逆变电源的起动性能．更多还原

【Abstract】 This paper discusses the way to improve the self-vibration start process of an inverter and puts forward a new inverter cercuit,which uses micro -processor and GTR or GTO in main bridge.The trigger pulse of this circuit is not relative to the load, as a result, the start property of the inverter is improved greatly .更多还原
