Introduction of structure and performance of thyristor three-phase power regulator


Three-phase power regulator is a kind of power control apparatus based on thyristor (power electronic power device) and intelligent digital control circuit, which is mainly used for three-phase 380VAC.


Power regulator uses digital circuit to trigger thyristor to realize voltage regulation and power regulation. Voltage regulation adopts phase shift control mode, power regulation has two modes: Power Regulation with fixed period and power regulation with variable period. The Control Board has such functions as synchronous circuit with Pll, automatic phase distinguishing, phase missing protection, power on slowly start, slow shut off, radiator over-temperature detection, constant current output, current limit, over-current protection, serial working state indication and so on.


Power regulator through the voltage, current and power control, thus achieving precision temperature control. And with its digital control algorithm, the optimization of power efficiency. Has played an important role in saving electric energy. Power regulator has many advantages, such as high efficiency, no mechanical noise and wear, fast response, small volume, light weight, etc. .
