In this paper, the authors present a Power Factor Corrected (PFC) variable DC converter fed BrushLess DC Motor (BLDCM) drive as a cost effective solution for low-power household applications. The variable DC converter operation is based on Canonical Switching Cell (CSC) topology. The speed of BLDCM is controlled by varying the DC-bus voltage of Voltage Source Inverter (VSI). The BLDCM is electronically commutated for reduced switching losses in VSI due to low-frequency switching. A front-end CSC converter operating in Discontinuous Inductor Current Mode (DICM) is used for DC-bus voltage control with unity power factor at AC mains.
