低成本的开关磁阻电机（SRM）驱动系统是积极寻求高效率的家用电器和电动工具。在功率变换器中，减少开关器件的数量是降低驱动成本的主要方法。每相单开关转换器由于转换器封装的紧凑性而具有成本效益，从而可能降低其成本。然而，一些每相单开关变换器具有包括较高损耗和低系统效率的缺点。为了克服这些缺点，选择缩小到分裂交流变换器通过定量分析在器件额定值，成本，开关损耗，导通损耗，和转换器效率。仿真验证了变换器电路的特性和控制的可行性。电机驱动采用新型的两相无磁链反转定子开关磁阻电机和分离式交流变换器。从子系统和系统的角度对不同负载下的效率进行了详细的数值估算和实验比较。并对空载和满载时的噪声进行了比较。本文的重点是通过实验比较所考虑的分裂交流变换器和不对称变换器，并证明分裂交流变换器在成本、效率和噪声方面是最有利的
Low-cost switched-reluctance-motor (SRM) drive systems are actively sought for high-efficiency home appliances and power tools. Minimizing the number of switching devices has been in power converters that is the main method to reduce drive costs. Single-switch-per-phase converters have been cost effective due to the compactness of the converter package resulting in a possible reduction in their cost. However, some of the single-switch-per-phase converters have the drawbacks that include higher losses and low-system efficiency. In order to overcome these shortcomings, the choice narrows down to the split ac converter through the quantitative analysis in terms of device ratings, cost, switching losses, conduction losses, and converter efficiency. Simulations to verify the characteristics of the converter circuit and control feasibility are presented. The motor drive is realized with a novel two-phase flux-reversal-free-stator SRM and a split ac converter. The efficiency with various loads is numerically estimated and experimentally compared from the viewpoint of subsystem and system in details. The acoustic noise with no load and full load is also compared. The focus of this paper is to compare the considered split ac converter to the asymmetric converter through experiments and demonstrate that the split ac converter is the most advantageous with respect to cost, efficiency, and acoustic noise
