Abstract :
It is known that if harmonic spectra are reduced, then acoustic noise also reduced. Hence, this paper proposes a new random switching strategy using DSP TMS320F2812 in order to reduce the harmonic spectra of a single phase 6/6 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 proposed method is then being simulated in Matlab/ Simulink environment. Furthermore, this algorithm has also been inspected on various switching frequency. The experimental results show that the proposed strategy provides better harmonic spectra performance than conventional strategies, i.e. And a good agreement between experimental and simulation results is obtained.
