The thyristor power controller adopts thyristor (SCR or TRIAC) as the switching component, namely, a non-contact switch that can quickly and accurately control the closing time. It serves as an essential terminal equipment for power control designed for high precision and high dynamic indicators. It is worth noting that different loads and constraints of the operation environment determine different control modes and require various supporting equipment. Among control modes there are phase angle control, distributed crossover and time proportional zero crossover. In actual use, SCR power controllers can be sorted into single-phase SCR power controllers and three-phase SCR power controllers in accordance with their load types, power supply types and power supply voltage levels. So, how should we choose the right type of power controller and bring its optimum performance into play with minimal damage? The following passages will give you the answer.
