ABSTRACT
In the quest of energy efficiency improvement, researchers have developed many new
electrical machines and permanent magnet brushless DC motors (PMBLDCMs) are one of
them. Their high efficiency, silent operation, compact size, high reliability and low
maintenance features make them a suitable choice for many industrial, commercial and
domestic applications. The advancement in geometries and design innovations has made
possible the use of PMBLDCMs in any shape and size to fit many of the domestic,
commercial and industrial applications. At present, PMBLDCMs are finding applications in
diverse fields such as household appliances, automobiles, transportation, aerospace
equipments, power tools, toys, healthcare equipments, sophisticated position control
applications and medium size industrial drives.
This research work aims on the power factor correction in the PMBLDCM drive for various
low power applications with speed control. The PMBLDCM requires a three-phase voltage
source inverter (VSI) to be operated as an electronic commutator based on the rotor position
signals of the PMBLDCM obtained using Hall effect sensors. The three-phase VSI of the
PMBLDCM drive (PMBLDCMD) is fed from a single-phase AC mains through a diode
bridge rectifier followed by a smoothening DC capacitor, which draws an uncontrolled
charging current resulting in a pulsed current from AC mains, thereby, many power quality
(PQ) disturbances arise at AC mains such as poor power factor (PF), increased total
harmonic distortion (THD) of AC mains current and its high crest factor (CF). Moreover,
various international standards such as IEEE 519, IEEE 1159 and IEC 61000-3-2 impose
strict limitations on the harmonic current emissions by various loads. Therefore, power
factor correction (PFC) converter based drive is essential for a PMBLDCM in most of small
rating domestic and commercial applications.
The selection of a PFC converter for feeding PMBLDCMD needs emphasis on conformity
to the PQ norms, cost, and performance of the controllers. There are many DC-DC converter
topologies available which can be used as PFC converters such as buck, boost and buck
boost converters with single switch, two-switch and four-switch converters with and without
high frequency transformer to name a few, forward, flyback, Cuk, SEPIC, Zeta, Push-pull,
Half-bridge and Full-bridge converters. The mostly used control schemes for PFC
converters are current multiplier control with continuous conduction mode (CCM) and
voltage follower control in discontinuous conduction mode (DCM) of operation. The current
v
multiplier control uses average current control strategy and yields good results as compared
to the voltage follower control. However, the voltage follower control requires less number
of sensors and has reduced control complexity.
In this research work, analysis, design and control of PFC converters for improvement of
power quality at AC mains are aimed for a PMBLDCMD. The other major emphasis of the
investigation is on simple control, reduced number of sensors and circuit components,
leading to reduction in overall cost. A wide range of PFC converter configurations for
PMBLDCMs are analyzed, designed and their performance is simulated for various
applications. For the possibility of sensor reduction in the existing PFC converter fed
PMBLDCMD, a novel DC link voltage control scheme is analyzed, designed and
implemented to demonstrate effective speed control of the PMBLDCM along-with
improvement in PQ at AC mains. These PFC converters are further investigated in DCM
operation with possible reduction of various sensors for PMBLDCMD.
A digital signal controller (DSC) dsPIC 30F6010 is used for validation of simulated
performance on a 2 hp, 5.2 Nm rated PMBLDCM. It is an easy to use and low cost
controller design platform which suits the requirements of PMBLDCMDs in various
applications. Test results have validated the simulation results while performing speed
control and PFC control from a single processor. The DC link voltage control scheme has
evolved out of this research work for the speed control of PMBLDCM which has resulted in
reduction of sensors in the
PMBLDCMD and has consistently shown improved power
quality at AC mains in wide range of speed and input AC voltage.
