KGDS type single-phase low temperature iron plated power supply circuit

KGDS type single-phase low temperature iron plated power supply circuit

Low-temperature iron plating is a new process that starts plating with asymmetrical alternating current at room temperature and then transitions to direct current plating.
    The circuit is shown in the figure. By adjusting the potentiometers RPi and RP2, the conduction angles of the positive and negative thyristors can be changed, thereby
allowing the AC asymmetry ratio to be adjusted arbitrarily. By operating the changeover switch S, symmetrical and asymmetrical AC and DC power supplies are available
.
    The technical parameters of this power supply unit are as follows.
    AC input voltage: 50Hz, 380V; input current: 25A; input power: 23. 7kV. A.
    DC output voltage: o～16V (average value); Output current : o～1000A (average value); Output power:
16kV. A.
    AC output current : positive half wave 500A ( rectified average value); negative half wave 500A (rectified average value); AC output
current: positive half wave 0~8V (rectified average value); negative half wave 0~8V ( rectified average value) value).
