Working Principle

The working principle of the rectifying bridge thyristor module is based on the two switches and four-wire three-phase AC power supply manner. UTP6A200VL contains a six-port control and drive device, which consists of two thyristors per phase and a small control device which is capable of providing the proper control for the thyristor. The two thyristors are connected through two antiparallel diodes and a resistor in series, which gives rise to the alternating current undergoes rectification when it passes through the thyristor bridge device. The control module is used to control the base current of the thyristor, so as to control the on/off action of the thyristor.
