双电流环交替控制的单相升-降压功率因数校正变换器研究
Research on Single-phase Boot-Buck Power Factor Correction Converter Controlled With Dual Indispensable and Alternately-effect Current Loop
摘要
Abstract
Working principle of single-phase Boost-Buck power factor correction converter was analyzed, and the current control method of the converter in pure Boost and pure Buck mode was analyzed also. A new dual-mode control scheme constituting average current mode control and charge control was proposed. With this control scheme, input current of the converter can be well controlled not only in Boost mode, but also in Buck mode when the peak input voltage is larger than the output voltage, and high input power factor can be achieved meanwhile. Diagram of the dual-mode alternative control scheme was given, and the realizing method of charge control in digital control system was proposed. Validity of the theory analysis and the control scheme was verified through experimental results. Research results of this paper are referable for the control of single-phase cascaded Buck-Boost converter.关键词
