A PFC Zeta Converter for Speed Control of PMBLDC Motor Drive

Abstract— This paper presents a Zeta DC-DC converter as a power factor correction (PFC) converter which is operated in voltage control mode for speed control of a permanent magnet brushless DC motor (PMBLDCM). The proposed converter performs the PFC action and DC link voltage control in single stage and needs only one controller. The proposed PMBLDCM drive (PMBLDCMD) is designed and modeled, and its performance is evaluated in PSIM environment. Simulated results are presented to demonstrate an improved power quality at ac mains of the PMBLDCM system in a wide range of speed and input ac voltage. Test results of a developed controller are also presented to validate the design and model of the drive.
