摘　　要：针对ACPL-32JT隔离光耦驱动芯片高集成度所带来的驱动隔离电源输出电压偏差大、不可调的问题,对其实际应用的电路参数进行了修正。通过对绝缘栅双极型晶体管(IGBT)门极驱动导通电压的测试验证,证明了修正后的电路能够有效地解决输出电压偏差大的问题,使电机控制器在批量生产过程中的稳定性与可靠性得到了有效的保障。In order to solve the problems of large variation range and non-adjustable of the output voltage while the isolated optocoupler driver chip ACPL-32 JT is highly integrated in drive circuit,a modification strategy was proposed by optimizing the circuit parameters for practical application. Through the test on the turning-on voltage of insulated gate bipolar transistor(IGBT),it is proved that the modified circuit can effectively solve the problem of large output voltage deviation,the stability and reliability of motor controller in mass production were effectively guaranteed.
