Mfundo ya PWM controller

Chisonkhezero cha mawonekedwe ofanana ndi osiyana a phokoso lopapatiza, lomwe linawonjezeredwa ku chiyanjano ndi inertia pamene ali ndi zotsatira zofanana.PWM ulamuliro mfundo: ndi kugawa waveform mu magawo 6 ofanana, amene akhoza m'malo ndi 6 lalikulu mafunde. Pali magulu ambiri a PWM, monga unipolar ndi bipolar, synchronous and asynchronous, rectangular and sinusoidal modulation, etc.

Unipolar PWM control imatanthauza kuti mkati mwa theka la kuzungulira, chonyamuliracho chimangosintha mbali imodzi, ndipo zotsatira za PWM waveform zimasinthanso mbali imodzi.Bipolar PWM control njira ndi unipolar mosiyana, iye ali mu theka la chonyamulira chonyamulira kusintha mbali ziwiri. kuti ngati chonyamulira chizindikiro ndi kusinthasintha chizindikiro kusunga kalunzanitsidwe, ulamuliro PWM akhoza kugawidwa mu synchronous kusinthasintha ndi asynchronous modulation.The khalidwe la amakona anayi zimachitika m'lifupi kusinthasintha ndi kuti linanena bungwe zimachitika m'lifupi mzere ndi wofanana m'lifupi ndipo akhoza kungolamulira chiwerengero china cha harmonics. .Makhalidwe a sinusoidal pulse width modulation ndi kuti kutuluka kwa pulse m'lifupi sikuli kofanana, m'lifupi kumasintha malinga ndi lamulo la sinusoidal, ndipo kutuluka kwa waveform kuli pafupi ndi sinusoidal wave.Sine pulse width modulation imatchedwanso SPWM. Pakalipano, njira yofananitsa mafunde a katatu, njira yofananira ya hysteresis ndind space voltage vector njira imagwiritsidwa ntchito kwambiri.
