Abstract: Some key technologies on phase-controller are analyzed. A controlled IGBT (Insulated Gate Bipolar Transistor) scheme of smart phase-controller with FPGA(Field Programmable Gate Array) is proposed to realize zero-crossing circuit breaker operation. In order to improve equipment anti-interference ability, differential control is used in each IGBT control circuit, and independent power source is adopted in drive circuit. The proposed scheme can be used in merging unit, intelligent terminal and phase-controller in smart station. Test results show that proposed intelligent phase selection controller has high reliability and broad application prospects.
