A novel PFC (Power factor Correction) converter using ZETA DC–DC converter feeding a BLDC (Brush Less DC) motor drive is proposed. A single phase supply followed by an uncontrolled bridge rectifier and a Zeta DC-DC converter is used to control the voltage of a DC link capacitor which is lying between the Zeta converter and a VSI (Voltage Source Inverter). Voltage of a DC link capacitor of Zeta converter is controlled to achieve the speed control of BLDC motor. The proposed PMBLDCM drive is designed and its performance is evaluated in Matlab– Simulink environment and the hardware is implemented on PCB.
