基于过载软压缩技术的逆变电源保护电路设计

摘要

In order to solve the problem of current overload in inverter power source,a protection circuit is designed. By sampling and comparing the output current of the inverter bridge circuit,the accurate control of the output current is realized. It is proved by experiments that this method can effectively protect the inverter.%为了解决逆变电源中存在的电流过载问题,设计了一种逆变电源保护电路.通过对逆变桥电路输出电流的取样与比较,实现对电源输出电流的精确通断控制.经实验验证该方法可以有效地实现逆变电源的过流保护.
