摘　　要：提出将模糊双闭环控制策略用于整流器以提高其功率因数,研究了影响整流器提高功率因数的因素,进而利用模糊推理技术和双闭环控制策略对功率因数和输出电压进行稳定控制,其结果明显优于单纯的PI控制和双闭环控制。The double closed-loop fuzzy control strategy was presented to improve the power factor in rectifier, and the effects of rectifier on the factors that improve power factor were studied. And then the fuzzy reasoning and double closed-loop control strategy was used to stably control the power factor and output voltage. The results show that the design is better than the PI control or double closed-loop control.
