Abstract:
This paper presents a Power Factor Correction (PFC) based Bridge less Canonical Switching Cell (BL-CSC) converter-fed Brushless DC (BLDC) motor drive. The BL-CSC converter works in a discontinuous inductor current mode in order to obtain a 0.99 power factor of operation. The speed control of the BLDC motor is achieved by adjusting the DC bus voltage using a PI controller. Voltage Source Inverter (VSI) is operated at the fundamental frequency for reducing the switching losses of BLDC motor electronic commutation. By the partial elimination of the diode Bridge rectifier at the front end the bridgeless configuration of CSC converter has low conduction losses. The proposed configuration is validated using a MATLAB simulation and laboratory experimental setup, which shows a considerable increase in the efficiency.
