High-Power-Factor AC/DC Communication Power Based on Double Closed-Loop PFC

Hu Lei,Chen Yong,Huang Qi,Li Jian(School of Automation Engineering,University of Electronic Science & Technology of China,Chengdu 611731,China)  
For the current phase of AC/DC communication power lag caused by nonlinear devices,resulting in low power factor and efficiency issues,presents the voltage and current double closed loop PFC techniques,to create control loops and power sectors of mathematical models to determine the power factor correction part of the regulator of the PI parameters,While the secondary side of the DC/DC converter using the double output flow and the phase shift control strategy.The input current of AC/DC power supply follows the sinusoidal line voltage,input power factor is about equal to 1,and more than 92% efficiency verified by experiment.
