How is the overcurrent protection of the circuit in the intermediate frequency circuit? If the load of the intermediate frequency power supply is short-circuited or the commutation of the inverter circuit fails, the three fully-controlled rectifier bridges will be used to short-circuit through the DC flat-wire welder. The short-circuit current flows through both the rectifier circuit and the inverter circuit.
