This paper introduces a novel design of three-phase AC-voltage regulation trigger circuitry using silicon controlled rectifier (SCR), and presents its application in an energy-saving design of oil extractor control system. The design employs photoelectric isolation technique and the inter-phase of three-phase power supply itself, only three groups of triggering signals are required to control the six thyristors conducting angles. The generation of high-precision triggering signals and PID control regulator functions are realized by programming the multiple high-performance timers and the AD interface of a STM32 microprocessor. Experiments and in-field tests have shown the feasibility of the proposed scheme.
