摘　　要：针对开关式交流稳压电源主电路复杂、功率小以及工频补偿式交流稳压电源体积大、精度低等问题,提出一种基于高频变压器的补偿式交流稳压电源。该稳压电源体积小,采用瞬时值移相调压控制方法和软件锁相环技术,可实现快速稳压、调频和补偿谐波的目的。Matlab仿真结果表明,新型交流稳压电源可控制稳压精度小于0.5%,谐波含量小于1.0%,且在0.02 s内完成调频。Aiming at the problems of the power supply, including the complex main circuit and small power of the switch mode AC stabilizer, and large volume and low precision of the compensation AC stabilizer, this paper pro- posed a new compensation AC stabilizer power supply based on high - frequency transformer. It is the stabilizer power supply that, with small volume, adopts the phase shift regulating control method and the software phase locked loop technique to realized fast voltage and frequency regulation and harmonic compensation. The simulation result through Matlab shows that by the new AC stabilizer power supply, the voltage precision can reach 0. 5% and the harmonic content being limited to less than 1%, and the frequency regulation being finished within 0. 02 s.
