Abstract :
A new tangentially sampling method of sinusoidal pulse width modulation is proposed in this paper, and the determination of sampling time and the harmonic of output voltage waves by DC-AC inverter under the new method are compared with those under the naturally sampling method and the regularly sampling method. The results show that the proposed method has advantages of simple calculation of sampling time and low output harmonic over the other two methods.
