PRR Soft Stater Principle introduction Three reverse-parallel connection SCR modules are adopted as power element. The soft starter can pick up synchronization signal from input voltage sampling, and realize feedback fuzzy control by output current sampling, trace the phase automatically and control phase displacement angle. Voltage can thus be increased step by step, and startup current will be under control. After startup, the bypass contactor will short-circuit the SCR. The motor will finally be driven into the electricity network for operation.
