This document details a power factor correction (PFC)-based bridgeless canonical switching cell (BL-CSC) converter that is used to power a brushless DC (BLDC) motor drive. The BL-CSC converter functions in discontinuous inductor current mode to maintain a unity power factor in the AC main, using only one voltage sensor. The speed regulation of the BLDC motor is achieved by altering the DC bus voltage of the voltage source inverter (VSI), which powers the BLDC motor through a PFC converter. Consequently, the BLDC motor is electronically commuted, allowing the VSI to operate at fundamental frequency switching, thereby minimizing switching losses. Additionally, the bridgeless design of the CSC converter reduces conduction losses by partially removing the diode bridge rectifier at the input stage. This proposed setup demonstrates a significant efficiency improvement compared to traditional methods. The performance of the proposed drive system is simulated and the results are gathered using MATLAB. Improved power quality is maintained on the AC mains over a wide spectrum of control speeds and input voltages.
