Abstract
In recent years, a wide variety of high-power-factor converter schemes have been proposed to solve the harmonic problem. The schemes are based on conventional boost, buck or buck-boost topology and their performance, such as output voltage control range in the boost and buck topology or efficiency in the buck-boost topology are limited. To solve this, the authors propose a single-phase high-power-factor converter with a new topology obtained from a combination of buck and buck-boost topology. The power stage performs the buck and buck-boost operations by a compact single stage converter circuit while the simple controller/modulator appropriately controls the alternation of the buck and buck-boost operation and maintains a high quality input current during both the buck and buck-boost operations. The proposed scheme results in a high performance rectifier with no limitation of output voltage control range and a high efficiency. In this paper, the principle and operation of the proposed converter scheme are described in detail and the theory is confirmed through experimental results obtained from a 2 [kW] prototype converter.
