Yadda inverter yake da Pulse Width Modulation (PMW) a yi?
Konseptin gaba na PWM (Pulse Width Modulation) shine ya kawo ciki gwamnati na fadada daidai a kan shaida a kan wata. Haka ne abubuwan da suka faru:
Shaida na Mafi Amfani (Carrier Signal): Inverteron da suke amfani da PWM suna amfani da wata na tsiraki (ko kuma sawtooth wave) na mafi amfani a matsayin shaida na mafi amfani, wanda ake kira carrier signal.
Shaida na Kiyaye (Modulation Signal): Shaida na kiyaye shine sine wave na musamman wanda ya nuna hanyar da suka duba AC waveform. Tsari na shaida na kiyaye na iya haɗa da tsarin fadada daidai, idan wannan tsari na iya haɗa da tsarin fadada daidai.
Dukkana: Shaida na kiyaye an dukki da shaida na mafi amfani. Idan ma'ana na zama na shaida na kiyaye yana da take da shaida na mafi amfani, ana samun output na high-level; bale ba sai, ana samun output na low-level.
Gwamna na PWM Waveform: A nan dukkantar, an samu wurare na rectangular waves na yankunan da suka badalawa. Yankunan da suke badala waɗannan wurare na rectangular waves a kan lokacin, wanda ya nuna karfin sine wave.
Filtaring: A nan duka, ana amfani da filter don ƙara muhimmin abubuwa na frequency daga PWM waveform, wanda ya ƙara output na sine wave mai kyau.
