Abstract: PMBLDC motor finds its application in various fields which includes hybrid electric vehicles, robotic applications with high precision control, fans and industries. This paper presents DSP based control with switching loss reduction technique for Permanent Magnet Brushless DC motor. Firing pulses for power switches are generated using DSP TMS320C2407 based on hall sensor feed-back. The algorithm is written in C using code composer studio to generate single mode PWM pulses and multiple PWM pulses. To reduce the switching losses three switches are turn on and turn off with single pulse and the remaining three switches are with multiple PWM pulses. The hardware is implemented and the trapezoidal stator voltage and corresponding gating signals are measured for various speed. The experimental results validate the performance of proposed system.
Keywords: PMBLDC, DSP Controller, Trapezoidal PWM.
