Ebe dị na ọkọnọ ọkụ ebe a chọrọ ihe ndị na-eduzi okpomọkụ:
1. The isi mgbawa nke ike ọkọnọ: isi mgbawa nke nnukwu ike ọkọnọ n'ozuzu nwere nnukwu ihe a chọrọ na okpomọkụ dissipation, dị ka UPS ike ọkọnọ, n'ihi na ya ike ike ọkọnọ ọrụ, isi mgbawa kwesịrị ibu ọrụ ike. nke igwe dum, n'oge a ga-achịkọta ọtụtụ okpomọkụ, n'ihi ya, anyị chọrọ thermal conductive ihe dị ka ezigbo thermal conduction usoro.
2. MOS transistor: MOS transistor bụ akụkụ kacha ukwuu na-ekpo ọkụ ma e wezụga isi mgbawa nke ọkụ ọkụ, ọ dị mkpa iji ọtụtụ ụdị ihe na-eduzi okpomọkụ, dị ka akwụkwọ mkpuchi ọkụ, mmanụ ọkụ, okpomọkụ okpomọkụ, wdg.
3. Transformer: Transformer bụ ngwá ọrụ ntụgharị ike, na-akwado ọrụ ntụgharị nke voltaji, ugbu a na nguzogide.Otú ọ dị, n'ihi arụmọrụ pụrụ iche nke transformer, ntinye nke ihe ndị na-eduzi okpomọkụ ga-enwekwa ihe pụrụ iche chọrọ.
