▍1. 直流稳压加保护
说明: 使用multisim软件设计的直流稳压保护电路,具有交流信号转直流信号,还进行了限压保护,最后通过光耦隔离器件作为开关,进行后续器件的驱动(The DC voltage stabilizing protection circuit designed by Multisim software has AC signal to DC signal and voltage limiting protection. Finally, the optical coupling isolation device is used as the switch to drive the follow-up device)
