摘　　要：传统Heric逆变器各个桥臂采用相同的驱动电路,造成保护功能的重复,文章针对Heric逆变电路上下桥臂的导通状态,对逆变器上、下桥臂驱动电路的功能进行了划分,分别设计了上、下桥臂驱动电路,使其实现互补配合的保护功能,并针对驱动电路中光耦隔离芯片输出失真的问题,在光耦输入侧加入驱动增强电路。对驱动电路进行测试,实验结果表明该驱动电路可靠性较高,在占空比变化范围较宽时失真度小,逆变器输出波形较好。The drive circuit used for each bridge arm of the traditional Heric inverter is same,which causes the repetition of the protection function. According to the conduction state of the upper and lower arms of the Heric inverter circuit,the functions of the upper and lower bridge arm drive circuits of the inverter are divided. The upper and lower bridge arm drive circuits are designed respectively to realize the function of complementary cooperation,and for the problem of output distortion of the driver circuit optocoupler isolation chip,a driving enhancement circuit is added to the optocoupler input side. The driving circuit is tested. Experimental results show that the drive circuit has higher reliability. The driving circuit can also reduce the distortion when the range of duty cycle is wide. The output voltage waveform of the inverter is good.
