Abstract

For conventional BLDCM direct torque control strategy existing many disadvantages, for example, flux ring observation algorithm is complex, electromagnetic torque ripple is too large, the current waveform is not ideal, high switching frequency and large switching losses are also serious, designing an improved BLDCM direct torque control strategy. it used different zero voltage vectors in a need to reduce the torque ripple. Simulation results showed that the improved strategy could suppress the freewheeling in non-conduction phase, and could effectively improve the current waveform, suppress torque ripple, and this strategy could also reduce the inverter’s chopping frequency, improve system reliability and reduce the switching losses of the device.
