Abstract :
The paper presents a novel circuit for generating the sine PWM control signals for a single phase inverter. Waveform generating ICs based on a JFET are used to generate the synchronized sine and triangular waveforms with a high accuracy and wide range of frequencies. Experimental waveforms and frequency spectra of inverter output voltage are presented
