LV AHF Yochepetsera Ma Harmonics mu Network Electrical Network

Poyang'anizana ndi vuto lalikulu la kuyipitsa kwamphamvu kwamphamvu, AHF ndiye chida chothandiza kwambiri pakuwongolera mphamvu zamagetsi. AHF ndi chida chatsopano chapadera chowongolera mphamvu zamagetsi chomwe chimapangidwa pogwiritsa ntchito ukadaulo wamakono wamagetsi amagetsi ndi ukadaulo wamakina a digito potengera zida za DSP zothamanga kwambiri. AHF ndi yofanana ndi jenereta yamakono ya harmonic, yomwe imatsata zigawo za harmonic mu mphamvu yamakono ndikupanga mafunde osakanikirana ndi matalikidwe ofanana ndi gawo losiyana.AHF ili ndi magawo awiri: malangizo omwe akugwiritsidwa ntchito panopa komanso chipukuta misozi cham'badwo wamakono. Dongosolo lomwe likugwira ntchito pano limazindikira zomwe zikuchitika mu nthawi yeniyeni, kutembenuza chizindikiro cha analogi kukhala chizindikiro cha digito, ndikuchitumiza ku purosesa ya digito yothamanga kwambiri (DSP) kuti ikasinthidwe. Mafunde a ma harmonic ndi ofunikira amasiyanitsidwa kuti apeze malangizo apano, omwe amatumizidwa ku chipukuta misozi cham'badwo wamakono mwa mawonekedwe a pulse wide modulation (PWM) chizindikiro kudzera mumayendedwe owongolera omwe akutsata ndikuyenda. Ma module amphamvu a IGBT ndi IPM amayendetsedwa kuti apange chipukuta misozi ndi matalikidwe omwewo ndi polarity yosiyana ndi ma harmonic pano, omwe amalowetsedwa mu gridi yamagetsi kuti athe kubweza kapena kuletsa ma harmonic pano, mwachangu kuthetsa ma harmonics amphamvu, ndikukwaniritsa mwamphamvu, mwachangu. , ndi kukonza mokwanira kwa ma harmonics amphamvu.
