Ko te mana whakawhiti kore he huarahi tino noa ki te whakahaere i temana whakahaere, ina koa ko te kawenga ko te momo parenga.
Ka whakakāhia, ka whakawetohia ranei te thyristor ka kore te ngaohiko, a ka taea te whakatika i te mana ma te whakatika i te ōwehenga o te thyristor i runga me te wa whakaweto.Ko te aratau whakawhiti kore ka taea e tatou te wehewehe ki te wa pumau te mana whakawhiti kore me te waa rereke te mana whakawhiti kore e rua nga huarahi.
Ko te aratau mana whakawhiti kore-kore (PWM zero crossing): Ko te waa-waahi-kore-whakawhitinga aratau ko te whakahaere i te mana toharite o te kawenga ma te whakatika i te huringa mahi i runga i te waa kua whakaritea.Na te mea ka whakahurihia, ka whakawetohia i te waahi kore o te hiko, i roto i te waahanga o te ngaru katoa, kaore he waahanga ngaru haurua, ka kore e whakaputa i te wawaotanga teitei, a ka taea te tae atu ki te mana o te mana, no reira he tino kaha. -whakaora.
Te wa taurangi te mana whakawhiti kore (CYCLE kore whakawhiti): Ko te waa rereke te aratau whakawhiti kore-kore he mana ano hoki i te whakawhiti kore o te hiko.Ka whakatauritea ki te aratau PWM, kaore he wa mana whakahaere, engari ka whakapotohia te waa whakahaere i te mea ka taea, ka wehewehea te auau kia rite ki te paheketanga whakaputa i roto i te waa whakahaere.Ano i roto i te ngaru katoa hei waeine, kaore he wahanga ngaru haurua, ka tae ki te tauwehe mana, engari ka penapena hiko.
Mai i te ahua i raro nei, ka tino marama te kite i raro i te aratau mana kore-whitiwhiti, hei whakatika i te mana whakaputa onga kaiwhakahaere mana, ka taea e tatou te whakatutuki i te kaupapa o te whakahaere i te mana ma te whakatika i te maha o nga huringa o te SCR i runga me te atu, he tino ngawari.Heoi ano, ka kite ano tatou he pai noa te mana whakahaere mo nga waahi kaore i te teitei te tika o te mana whakahaere, mena he tiketike nga whakaritenga whakahaere, kaore e pai te tikanga whakahaere auau.
