An isolated Zeta converter is proposed as a power factor correction (PFC) converter with DC link voltage control for speed control of a permanent magnet brushless DC motor (PMBLDCM). The voltage source inverter (VSI) is used as an electronic commutator of PMBLDCM. The proposed converter performs the PFC action and DC link voltage control in single stage using only one controller. The current multiplier...
This paper aims at a power factor corrected (PFC) buck bridge DC-DC converter for a permanent magnet brushless DC motor (PMBLDCM) for an air conditioner. This PFC converter is fed from a single-phase AC mains through a diode bridge rectifier (DBR) and connected to a voltage source inverter (VSI) feeding the PMBLDCM. The Speed of the proposed PMBLDCM drive is controlled to improve efficiency of the...
