Sinusoidal Pwm A Triangular Carrier Wave And Sinusoidal Reference One of the methods used to reduce the low frequency harmonics in the inverter waveform is sinusoidal pulse width modulation. in this method, a reference copy of the desired sinusoidal waveform, the modulating wave, is compared to a much higher frequency triangular waveform, called the carrier wave. The inverter is controlled with the sinusoidal pulse width modulation (spwm) technique as shown in figure 4 a to generate suitable pulses (figure 4 b) and an accurate sine wave signal.

This article explores the potential of carrier based pulse width modulation techniques such as sawtooth, triangular, and sinusoidal, and examines how they directly impact harmonic distortion in high voltage inverters. In this pwm technique, the sinusoidal ac voltage reference is compared with the high frequency triangular carrier wave in real time to determine switching states for each pole in the inverter. Sinusoidal pulse width modulation (abbreviated as spwm) is a more complex type of pwm. in figure 29, spwm generates a pulse train for each gating signal g1 and g4 by comparing a sinusoidal reference signal with a triangular carrier signal.

My main question is understanding the mathematical proof or the underlying logic behind why the intersection of the triangle wave with the sine wave results in a pwm that carries the sine's frequency. In order to implement sinusoidal pwm using analog circuits, one has to use the given building blocks (1) triangular wave generator (2) sinusoidal wave generator (3) comparator (4) inverter circuits. The reference signal, also known as a modulating or control signal, in this case a sinusoidal, and the carrier signal, a triangular wave that regulates the switching frequency, are needed to control the switches for sinusoidal pwm output.
