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...
In this paper, a buck half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The PMBLDCM is used to drive a compressor load of an air conditioner through a...
This paper deals with implementation of vector controlled induction motor drive (VCIMD) using DSP TMS320F240 and a comparison between proportional integral (PI) and fuzzy pre-compensated proportional integral (FPPI) speed controllers. The power circuit consists of a three-phase IGBT based voltage source inverter (VSI) feeding a three-phase squirrel cage induction motor. The control circuits consist...
This paper presents a critical analysis of intelligent tuned PID controllers for the permanent magnet synchronous motor drive. The PID proportional-integral-derivative (PID) controller is the most popular controller in process industry. The PID algorithm is simple, reliable and robust for the control of first and second order processes and even high order processes with well damped modes. In this...
Series active filtering has been identified as an appropriate solution for voltage fed type harmonic producing loads. Moreover, the amicable configuration demands employment of a set of shunt connected passive filters so as to suitably compensate harmonics and retain the characteristics of multiple diverse connected loads. This paper presents experimental study of series hybrid filter system (SHF)...
