Multiple Pulse Width Modulation (MPWM)
1 Answer
written 4.9 years ago by |
In this method of pulse-width modulation, the harmonic content can be reduced using several pulses in each half-cycle of output voltage. By comparing a reference signal with a triangular carrier wave, the gating signals are generated for turning. on and turning-off of a thyristor, as shown in Fig.1(a). The carrier …
