The protection circuit is generally composed of various components such as relays and signal indicating devices. When selecting power electronic switching devices, a certain margin should be left to ensure the safe and reliable use of the devices. At the same time, a protection circuit must also be provided to prevent device damage caused by faults. The protection circuit mainly includes overcurrent protection, overvoltage protection and overheat protection;
