In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...

Brushless DC (BLDC) motors are electronically commutated motors that offer many advantages over brushed DC motors and, therefore, are becoming very popular industrially and commercially. This application report discusses a sensored 3-phase BLDC motor control solution using MSP430TM as the motor controller. Hall sensors are used to detect the rotor position and close the commutation loop. Both o...

Water supply system consumes large amount of power load during water treatment and transportation of purified water. Many energy conserving high efficiency materials such as DC motor and LED light have recently been introduced to water supply system for energy conservation. This paper performed empirical analysis on BLDC and AC motors and comparatively analyzed the change in power according to ...

Abstract: Over the years, it has seen the power conditioning move from simple, but extravagant linear regulators, through early low frequency pulse-width modulated systems, to high-frequency square wave converters, which pack the same power handling capabilities of earlier designs into a fraction of their size and weight. At present, a novel attack is upon us the resonant mode converter and whi...

to meet increasing demand for higher reliability in power electronics converters applicable in electric vehicles, fault detection (FD) is an important part of the control algorithm. In this paper, a model based open transistor fault diagnosis method is presented for a voltage-source inverter (VSI) supplying a five-phase PM motor drive. To realize this goal, a model based observer is designed to...
