Harmonics Reduction by Single-pulse Width Modulation.
1 Answer
written 4.9 years ago by |
In the case of single-pulse width modulation, the width of the pulse is adjusted to reduce the harmonic. In general, the RMS value of the amplitude of harmonic voltage of a single pulse modulated wave is given by.
$$E_{L n}=\frac{4 E_{\mathrm{dc}}}{\sqrt{2} n \pi} \sin \frac{n p}{2}=\frac{2 \sqrt{2} E_{\mathrm{dc}}}{n \pi} \sin …
