imikhiqizo

I-Introduction Power Systems eyakhiwa ngaphambi kukaNovemba 1994 yasebenzisa i-Power Supply Module enombala omnyama futhi yakhiqizwa yi-Cherokee Company. I-Power Supply Module ine-crest factor ephakeme kune-Power Supply Module esetshenziswa njengamanje Ohlelweni Lwamandla. I-Power Supply Module yamanje inombala osiliva futhi yakhiwe yi-Bikor Corporation. Ukukhiqiza kwangaphambi kwesikhathi Imojuli Yokuhlinzeka Ngamandla Isici esidala seMojula Yokuhlinzeka Amandla weCherokee enombala omnyama ngu-2.2. Lokhu kusho ukuthi ukudonsa kwamanje okuvela kulayini wamandla we-ac akuyona i-sinusoidal kodwa kunenani eliphakeme eliphindwe izikhathi ezingu-2.2 kunenani lamanje le-rms. Umthwalo womugqa unenani eliphakeme lamanje elingu-1.414 izikhathi zevelu ye-rms; ngakho-ke, inani eliphakeme kakhulu lomdwebo wamanje ovela emugqeni we-ac walolu hlobo Lwemojula Yokuhlinzeka Ngamandla liphakeme ngokuphindwe izikhathi ezingu-1.6 kunalokho obekungaba njalo uma Imojula Yokuhlinzeka Ngamandla ingumugqa ophelele. Ukukhiqizwa Kwakamuva Imojuli Yokuhlinzeka Ngamandla Isici se-crest ye-Bikor Power Supply Module enombala osiliva ngu-1.7 (isimo esibi kakhulu). Isilinganiso esiphezulu esithathwe entanjeni yamandla e-ac siphindwe izikhathi ezingu-1.7 kunevelu yamanje ye-rms. Inani eliphakeme kakhulu lomdwebo wamanje ovela emugqeni we-ac Wemojula Yokuhlinzeka Ngamandla liphakeme ngokuphindwe izikhathi ezingu-1.2 kunalokho obekungaba njalo uma Imojula Yokuhlinzeka Ngamandla ingumugqa ophelele. Usayizi womthombo wamandla we-AC Usayizi wesiguquli sesiteshi esincane se-ac kanye/noma i-UPS ukuze uvumelane nomthamo wamanje omkhulu kune-rms yamanje. Lokhu kuzovimbela inkinga yokuhlanekezela ku-voltage kalayini okubangelwa ama-spikes amanje emthwalweni. Izinqamuli zesekethe namakhondaktha asalinganiswa ngokusebenzisa amanani e-rms. Isiguquli sesiteshi esincane kanye/noma i-UPS kungenzeka ihlinzeka ngamandla emithwalweni ehlukene endaweni enezici ezihlukile ze-crest. Ukuze usayizi ofanele wesiguquli sesiteshi esingaphansi kanye/noma i-UPS, kufanele ubale i-crest factor yomthwalo ohlanganisiwe. Ukuze wenze lokhu, bala inani eliphezulu lamanje kanye nesamba se-rms samanje kuyo yonke imithwalo. I-aggregate load crest factor yinani lawa manani amabili.
