Development and Comparative Analysis of a Pulse-Width Modulation Strategy

A pulse-width modulation (PWM) strategy used to generate a control signal for an electronic switching inverter is described. A triangular timing wave of frequency f=6.N.F is used where F is the reference wave frequency, and N≥ 1 is an integer. The polarity of the timing wave is the same as the polarity of the half period of the reference wave. A comparative analysis is presented of the PWM signal generated with this strategy with respect to a similar signal generated by means of a "traditional" triangular modulation strategy.
