Optimal PWM problem
Original language description
Optimal pulse width modulation (PWM) problem, or as sometimes called selected harmonic elimination (SHE) problem, is an established method of generating pulse width modulation waveforms with low baseband distortion. Key issue is to determine the switching times (angles) so as to produce the signal portion (baseband) and not generate specific higher order harmonics. A spectral gap (guard band or zero band) separates the signal portion which has to be identical to the required output signal, from a uncontrolled frequency portion. The required output signal can be recovered by means of a analog low-pass filter (LPF) with cutoff frequency in guard band.

Optimální PWM problém
Czech description
Optimální pulzně-šířkově modulovaný (PWM) problém je metoda generování PWM signálu s malým zkreslením základního pásma. Základní problém je ve výpočtu spínacích časů, tak aby základní pásmo vyhovovalo zadání a navíc zde byla dostatečná mezera vyšších harmonických.
