固态功率控制器（ SSPC）是集断路器线路保护功能和固态继电器可靠性于一体的智能开关装置，具有开关速度快、无触点、无电弧、可靠性高等特点。为此，以基于绝缘栅双极型晶体管（ IGBT）反向串联结构为交流功率开关，研制了交流固态功率控制器。应用交流－直流真有效值转换芯片AD736，将传感器的输出直接转换为直流信号，省去了前端复杂的信号调理电路，简化了设计，并且有效地降低了寄生电容和杂散电容的影响。实验表明：设计的交流固态功率控制器原理样机满足测量精度要求，并验证了对负载反时限过流保护功能。

Solid state power controller ( SSPC) is a solid state device which is used to replace the relay’s role of switching and the breaker’s role of protection.It’s a switch matching with solid state distribution system.SSPC has the advantages of no noise, reacting quickly no electronic contact,no electronic arc,high reliability and so on.Therefore,an AC power switch based on insula-ted gate bipolar transistor(IGBT) at reverse tandem structure was presented.By replacing the complex signal processing circuit, AC-DC converter AD736 was used to convert capacitance sensor output into digital signal directly,simplify the electronics,and minimiz the interference of distributed and parasitic capacitance.Experiment result shows that the system meets the requirement of accuracy,and acquires good performance on the over-current protection of inverse-time.
