Working Principle The control circuit of cutting machine adopts advanced electronic part IGBT as the main inverter switch component. Three-phase AC power is converted to 40 kHz 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 diode.
