A power factor correction (PFC) based Landsman converter in bridgeless (BL) configuration feeding a brushless DC motor (BLDCM) drive is proposed for low power household appliances. The speed of BLDCM is controlled by varying the DC bus voltage of the voltage source inverter (VSI) feeding to a BLDCM. Switching losses of six solid-state switches of VSI are reduced by the use of low frequency switching signals in electronic commutation for the motor. The front-end bridgeless PFC based Landsman converter operating in discontinuous inductor current mode (DICM) is used for DC bus voltage control and PFC is achieved inherently with reduced conduction losses and switch stress. The DC bus voltage of drive is sensed by a single DC voltage sensor. A prototype is developed for performance evaluation of the drive for speed control over a broad range. The experimental performance of BLDCM is presented for its functions at wide voltages of AC mains (90V-265 V) to adhere the limits of standard IEC 61000-3-2.
