Ko te PWM (Pulse Width Modulation) he tikanga e whakamahia whānuitia ana hei whakahaere i te tere me te kaha wiri o ngā motuka DC, wiri rānei. Ina tukuna he tohu PWM auau teitei ki tētahi motuka, ko te ngaohiko toharite e akiaki ana i te motuka ko taua tohu. Mā tēnei ka taea te whakahaere tika i te tere me te kaha wiri o te motuka. He taputapu nui tēnei i roto i ngā momo tono tae atu ki te karetao, ngā mīhini ahumahi, me ngā hikohiko kaihoko.
Kia mārama ki ngā kaupapa matua o ngā tohu PWM
Hei whakamahi i te PWM hei whakahaere i te tere me te kaha wiri o te motuka, he mea nui kia mārama ki ngā kaupapa matua o ngā tohu PWM. Ko te tohu PWM he raupapa o ngā pātere, ko te whānui o te pātere (e kiia nei ko te huringa mahi) e whakatau ana i te ngaohiko toharite e pā ana ki te motuka. Mā te whakarerekē i te huringa mahi o te tohu PWM, ka taea te whakahaere i te ngaohiko me te iahiko whai hua e tukuna ana ki te motuka, ā, mā reira ka whakarerekē i te tere me te kaha wiri o te motuka.
Ina whakamahia te PWM ki tētahimotuka wiri moni, he mea nui te auau o te tohu PWM ki te whakatau i te mahi a te motuka. Mā ngā auau PWM teitei ake ka taea te whakahaere maeneene ake, te tika ake hoki o te tere me te kaha wiri o te motuka. Hei tāpiri, me āta whiriwhiri te auau PWM kia kore ai e pāngia e ngā pānga kino pēnei i te haruru e rangona ana, te haruru ā-pūkaha rānei i roto i te motuka.
He tauira o te motuka e peia ana e te tohu PWM
Kōwhiria te pūmana PWM tika, te pūmana iti rānei
Hei whakamahi tika i te PWM hei whakahaere i te tere me te kaha o te wiri o te motuka, me whiriwhiri he kaiwhakahaere PWM, he kaiwhakahaere iti rānei e tika ana hei whakaputa i te tohu PWM e hiahiatia ana. Me taea e te kaiwhakahaere te whakaputa i te tohu PWM auau-teitei me te huringa mahi ka taea te whakarerekē. Kia taea ai e ia te whakatutuki i ngā whakaritenga motuhake o te tono.
Hei tāpiritanga, he mea nui kia whakaarohia temotuka wiri itingā whakatakotoranga me ngā āhuatanga whakahaere i te wā e whakatinana ana i te mana whakahaere PWM. Me whai whakaaro ki ngā āhuatanga pēnei i te ngaohiko, te iahiko, te miihini, me te hiko o te motuka kia pai ai te whakahaere me te haumaru.
Ngā huringa mahi PWM
Hei whakarāpopototanga
He taputapu kaha te PWM mō te whakahaere i te tere me te kaha wiri o teMōta wiri DCMā te mārama ki ngā mātāpono o ngā tohu PWM me te whiriwhiri i tētahi kaiwhakahaere PWM e tika ana, ka taea te whakatutuki i te whakahaere tika me te pono o te mahi a te motuka. He hangarau tino nui tēnei i roto i ngā tono whakahaere motuka me te wiri.
Kōrero ki ō Tohunga Kaiārahi
Ka āwhina mātou i a koe ki te karo i ngā mahanga hei whakatutuki i te kounga me te uara o tō motuka paraihe iti e hiahiatia ana, i te wā tika me te tahua.
