Ukuze unciphise futhi ususe ukuphazamiseka kwe-harmonic yamanje ekhiqizwe ekugcineni kokufakwa kokushintsha okuthe xaxa yinda kwigridi yomphakathi nezinye izinto zikagesi, Yehlisa umthamo olinganiselwe we-Front-Stage Ac Isipele Sokunikezela Amandla Nemishini Yokusabalalisa Amandla, Gcina Ukutshalwa Kwemishini, Isinxephezelo Se-Power Factor (I-PFC) Sekuphenduke isidingo esisebenzayo sokushintsha okuphezulu kokushintshana okuphezulu. Isici samandla okufaka sokushintsha okuphezulu okuphezulu nge-rexif enesinxephezelo samandla asebenzayo angafinyelela 0.99 noma ngaphezulu, Futhi lapho isici samandla okufakwayo sifinyelela 0.999, I-harmonic yokufaka yamanje ye-rexifier ingancishiswa ibe ngaphansi kwalokho 3%, okuyingozi kugridi yombuso neminye imishini kagesi ngeke ibangelwe noma yikuphi ukuphazamiseka.

Ngokombono wokuqapha kanye nokuphathwa kwemvelo yamandla egumbini lekhompyutha yi-Communication Bureau, Kusetshenziswa inethiwekhi ukubheka kakhulu i-Power Environment System yegumbi lekhompyutha esikhundleni sokuphathwa ngesandla sekuyindlela yokuphatha yohlelo lwamanje lokuxhumana lokuxhumana. Selokhu 1993, Izinhlelo zokuqapha ezihlanganisiwe zokuhlinzekwa kwamandla nemishini yokufaka umoya zisetshenziswe kwamanye amahhovisi ocingo amade kanye namahhovisi ocingo endawo. Ukwakhiwa kohlelo lokuqapha olusemqoka lwemvelo yamandla yegumbi lekhompyutha sekuyindawo eshisayo ekuphathweni kwezinhlelo zanamuhla zokuxhumana zamandla. Okwamanje, Imikhiqizo yamandla okuxhumana eyenziwe abakhiqizi abahlukahlukene basekhaya, njengemvamisa ephakeme eshintsha ama-rexiaiers nezinhlelo zawo, I-AC UNGERREFFICAL WOVERVIes (Phezulu) kanye ne-inverter Power Supplies, Zonke zinemisebenzi yokuqapha kanye nezinqubomgomo zokuxhumana ezihambisanayo. Ngenxa yezizathu ezahlukahlukene, Ukuqashwa kwendawo yamandla yegumbi lekhompyutha yegumbi ngalinye lokuxhumana akuzange kuqhutshwe ngaphansi kweprothokholi yokuxhumana enobunye futhi esebenzayo. Iningi labakhiqizi bamandla bamandla banazo zombili izinqubomgomo zokuxhumana ezijwayelekile ezakhiwe embonini yezokuxhumana kanye nezinqubomgomo zokuxhumana ezakhiwe ngamabhizinisi ngokwazo. Kwezinye iziteshi zokuxhumana ezisebenzisa iphrothokholi yokuxhumana ehlanganiswa ngumenzi ukubona ukuqapha okuphakathi kohlelo lokunikezela ngamandla, Ukulinganiselwa kwephrothokholi yezokuxhumana kuzodala imikhawulo ekukhetheni, ukuguqulwa kanye nokufakwa esikhundleni kwemishini yokuhlinzekwa kwamandla.
