Abstract :
The area equivalent principle is simple to generate sinusoidal pulse width modulation (SPWM) waves. The SPWM waves that are generated by output of pulse width modulation (PWM) in single-chip microcomputer or digital signal processor (DSP) are analyzed harmoniously. In the SPWM waves there are PWM waves of same duty ratio per small equal time. There are different duty ratios in different small equal time. Actual SPWM waves are unfurled by the discrete Fourier series (DFS) with a computer. The analytic results of harmonics are more accurate and worth
