        Part?two of?Installation and Operation Instructions?of KHA—150A/150V Polarization Power Supply Devic

        Ⅱ.Working Principle:

        ??????The circuits of this device can be divided into main circuit and control circuit.

        2.1 Main circuit:

        ????As shown in the figure, the three-phase bridge rectifier circuit is used as the main circuit, the valve side of which is equipped with opening and closing surge absorber circuits and each arm is centrally provided with commutating overvoltage protection circuit. The three-phase AC voltage is reduced through a rectifier transformer and rectified by a thyristor before outputting the DC current 150A and voltage 150V.

        2.2 Control circuit: (as shown in the figure)

        ????It is composed of the fault signal detection circuit and trigger circuit.

        2.2.1 Fault signal detection circuit:

        Current overload: in case of major loop circuit overload, the trigger pulse will be blocked until fault clearance.

        2.2.2 Trigger circuit
