摘要：

This paper presents the design and control of a single-stage charge-regulated varying-frequency flyback switch-mode rectifier (SMR). First, the ratings of key constituted circuit components are derived, and accordingly, the power circuit is designed and implemented. Then, a novel charge-regulated, varying-frequency, current-controlled pulsewidth modulation (CCPWM) switching scheme is developed. In the proposed control scheme, the switch turn-on time is fixed, and the turn-off time interval is determined by the comparison result between the low-pass filtered switch current and its current command. The proposed switching scheme possesses the features of without slope compensation, having more dispersedly distributed harmonic spectrum, robust current tracking control, and ease of implementation using off-the-shelf integrated circuits. Finally, the quantitative and robust voltage regulation controls considering nonlinear behavior are made. Good dc output voltage regulation and ac input power quality control performances under wide load range are obtained. Some simulated and measured results are provided to demonstrate the performance of the developed SMR.
