Abstract

Brushless DC (BLDC) motors are typically driven by a voltage source inverter (VSI), which can be fed by an AC-DC step-down power factor correction (PFC) converter for a high power factor (PF). However, the prior-art bridgeless buck PFC converter has poor PF due to the input current dead zones. Thus, this paper proposes a novel step-down bridgeless PFC topology by arranging the buck and buck-boost converter cells in parallel. Due to the parallel configuration, the input current dead zones can be eliminated by the buck-boost operation, resulting in high PF over a wide output voltage range. The operation modes of the proposed topology are introduced, followed by the analysis of the input current and power processing. Integrated magnetic (IM) designs of the inductors, efficiency analysis, and the developed motor drive system control method are presented. Finally, the proposed and the bridgeless buck PFC converters are built and compared, along with a BLDC motor drive system, to verify the feasibility and features of the proposed converter.

基于并联变换器单元的无桥无刷直流电机宽输出降压PFC变换器

无刷直流（BLDC）电机通常由电压源逆变器（VSI）驱动，该逆变器可以由AC-DC降压功率因数校正（PFC）转换器提供高功率因数（PF）。然而，由于输入电流死区，现有技术的无桥降压PFC变换器具有较差的PF。因此，本文提出了一种新的降压无桥PFC拓扑结构，通过并联布置降压和降压升压变换器单元。由于并联配置，输入电流死区可以通过降压升压操作消除，从而在宽输出电压范围内产生高PF。介绍了该拓扑的工作模式，分析了输入电流和功率处理。介绍了电感器的集成磁设计、效率分析以及所开发的电机驱动系统控制方法。最后，构建了该变换器和无桥降压PFC变换器，并与无刷直流电机驱动系统进行了比较，验证了该变换器的可行性和特点。
