摘要
介绍了光电耦合器件HCPL-3120和HCPL-316J的功能和特点。三相电压型逆变器的每相均由上下桥臂(两个IGBT)组成,采用HCPL-3120驱动IGBT模块(BSM10GP120)的上桥臂,采用HCPL-316J驱动IGBT模块的下桥臂。HCPL-316J具有过流、欠压保护功能,能对IGBT模块提供及时保护。实验证明,该驱动方法具有较高的稳定性和良好的保护功能。
The function and feature of the optocoupler driver HCPL-316J and HCPL-3120 are introduced respectively in this paper.Every phase of three-phase voltage type inverter is composed of up and low arm（two IGBT）,using HCPL-3120 to drive the up ann of IGBT module （BSMIOGP120）, Using HCPL-316J to drive the low ann of IGBT module.HCPL-316J features overcurrent and under voltage protection,it can carry out timely protection for IGBT module. It has been proved that the driving design features the high reliability and the nice protection function.
