Description
Summary:This paper proposes a new random switching strategy using DSP TMS320F2812 in order to reduce the harmonics spectra of a single phase switched reluctance machine. The proposed method combines random turn-on, turn-off angle technique and random pulse width modulation technique. A harmonic spread factor (HSF) is used to evaluate the random modulation technique. The experimental results show that the harmonic intensity of output voltage for the proposed method is better than that for conventional methods.
