A voltage-controlled canonical switching cell-derived DC–DC converter with improved power quality feeding a variable speed permanent magnet brushless direct current (PMBLDC) motor-drive system for home appliances, is presented in this study. The converter is operating in the continuous conduction mode (CCM). This converter has less stress on the converter devices due to CCM of operation. A single converter is used for both the power factor correction (PFC) and the speed control of the drive, thus reducing the number of elements in the system. The speed control, along with PFC in this system is achieved via a PI controller having speed reference as an input. This system is capable of providing the low speed to rated speed operation while maintaining a unity power factor. The Hall-effect sensor-based electronic commutation of a PMBLDC motor-drive is implemented at the fundamental frequency. This significantly improves efficiency by reducing the switching losses of the voltage source inverter. A prototype of it is developed in the laboratory for implementation of the scheme. Simulated and real-time experimental results of the scheme are presented here for performance validation at various dynamic and steady-state operating conditions.

电压控制的功率因数校正CSC衍生的DC-DC转换器，用于PMBLDC驱动的家用电器

这项研究提出了一种电压控制的规范开关单元衍生的DC-DC转换器，具有改善的电能质量，可为家用电器提供变速永磁无刷直流（PMBLDC）电动机驱动系统。转换器以连续导通模式（CCM）运行。由于运行CCM，该转换器对转换器设备的压力较小。单个转换器用于功率因数校正（PFC）和驱动器的速度控制，因此减少了系统中的元件数量。速度控制以及该系统中的PFC是通过将速度参考作为输入的PI控制器来实现的。该系统能够在保持单位功率因数的同时提供低速至额定速度的运行。PMBLDC电动机构的基于霍尔效应传感器的电子换向在基本频率上实现。通过减少电压源逆变器的开关损耗，可以显着提高效率。它的原型是在实验室中开发的，用于实施该计划。此处提供了该方案的模拟和实时实验结果，用于在各种动态和稳态操作条件下进行性能验证。
