Work principles
The control circuit of cutting machine adopts advanced electronic part IGBT as the main
inverter switch component. Three-phase AC power is converted to 20KHz high-frequency DC
current after being rectified by three phase rectifier. Then under the function of IGBT inverter
the DC current is inverted to AC high frequency current, which is inverted to DC current after
experiencing voltage reduction in high frequency transformer, current rectifying in fast recovery
