Real Implementation of a Single Sensor based PFC with Novel Converter Fed BLDC Motor Drive

This paper proposed scheme for the Sensor-less BLDC motor drive fed by a Zeta based PFC converter operating in DICM. The front end Zeta DC-DC converter maintains the DC link voltage to a set reference value. Switch of the Zeta converter is to be operated at high switching frequency for effective control and small size of components like inductors. A sensor-less approach is used to detect the rotor position for electronic commutation. A blind startup is used for starting the BLDC motor. A high frequency MOSFET of suitable rating is used in the front end converter for its high frequency operation whereas an IGBT's (Insulated Gate Bipolar Transistor) are used in the VSI for low frequency operation. The proposed scheme maintains high power factor and low THD of the AC source current while controlling rotor speed equal to the set reference speed. citation: Jenopaul P, St.thomas college of engineering and technology; Sreehari ,St.thomas college of engineering and technology.
