Iko Kuchinja Kwemagetsi Kuri Nani Kupfuura Transformer?

Iyo switching power supply yakanaka.

Kuchinja magetsi kune zvakanakira zvitatu, sezvinotevera:

1) Kuderera kwesimba rekushandisa uye kushanda kwakanyanya.Mumagetsi ekushandura magetsi, pasi pekunakidzwa kwechiratidzo chekusimudzira, transistor V inoshanda zvakasiyana-siyana mu-on-off uye pa-off-off switching states.Iyo yekutendeuka inomhanyisa inokurumidza, uye frequency inowanzoita 50kHz.Mune dzimwe nyika dzine tekinoroji yepamusoro, mazana kana ingangoita 1000kHz inogona kuwanikwa.Izvi zvinoita kuti simba rekushandisa rekushandura transistor V rive shoma, uye kushanda kwesimba rekushandisa kunogona kuvandudzwa zvikuru, iyo inogona kusvika 80%.

2) Saizi diki uye uremu huremu.Kubva pane dhizaini yedhizaini yekuchinja magetsi, zvinogona kuoneka zvakajeka kuti hapana inorema simba frequency transformer inoshandiswa pano.Sezvo simba rakaraswa pachubhu yekugadzirisa V rakaderedzwa zvakanyanya, sink yakakura yekupisa inosiyiwa zvakare.Nekuda kwezvikonzero zviviri izvi, iyo yekuchinjisa magetsi idiki muhukuru uye huremu huremu.

3) Yakasiyana-siyana yekudzikamisa voltage.Iyo inobuda voltage yevaranda inoshandura magetsi inodzorwa neiyo basa kutenderera kwechiratidzo chekusimudzira, uye shanduko yemagetsi ekuisa chiratidzo inogona kubhadharwa ne frequency modulation kana hupamhi modulation.Nenzira iyi, kana simba remagetsi grid voltage richichinja zvakanyanya, rinogona kuramba rakagadzikana kuburitsa voltage.Naizvozvo, iyo voltage inodzikamisa huwandu hwekuchinja magetsi yakakura kwazvo uye iyo voltage inodzikamisa mhedzisiro yakanaka kwazvo.Mukuwedzera, kune nzira mbiri dzekushandura kutenderera kwebasa: pulse width modulation uye frequency modulation.Iyo yekuchinjisa magetsi haingove nemabhenefiti ehupamhi voltage kudzikamisa huwandu, asi zvakare ine nzira dzakawanda dzekuona kudzikamisa kwemagetsi.Vagadziri vanogona kusarudza zvakasiyana-siyana mhando dzekuchinja magetsi zvichienderana nezvinodiwa zvekushandisa zvinoshanda.

Ndinovimba inogona kukubatsira.
