Ukukhuthaza ukuqhubela phambili kweteknoloji yokugcina amandla kunye nokwandisa ukusetyenziswa kwamandla: ii-YMIN capacitors

Kwixesha elitsha lamandla, ukukhula okukhawulezayo kweenkqubo zamandla kuye kwaqhuba uphuhliso olukhawulezayo lweenkqubo zokugcina amandla.

Kwiinkqubo zokugcina amandla, amandla kunye neemfuno zesantya sokuphendula zamacandelo abalulekileyo (njengama-inverters, abaguquli, iinkqubo zokulawula ibhetri, njl.) Zihlala zikhula, nto leyo eyenza umngeni onzima kumacandelo e-elektroniki. Ii-Capacitors ezinomsebenzi ongcono, ubuninzi bomthamo ophezulu kunye nokuzinza okuqinileyo kuyafuneka ukuxhasa iinkqubo zokugcina amandla ukugcina ukuzinza okugqwesileyo kunye nokuthembeka kwiindawo ezahlukeneyo.

INXALENYE.01 i-inverter yokugcina amandla

Indima inverter kwinkqubo yogcino amandla ikakhulu ukuguqulwa amandla, ulawulo kunye nonxibelelwano, ulawulo amandla, njl Ikakhulu isebenzisa capacitors nge high capacitance ingxinano, ukuxhathisa iripple yangoku kunye nokumelana ombane aphezulu ukudlala indima yozinzo ombane kunye nokuhluzwa, ukugcinwa kwamandla kunye nokukhululwa, kunye ne-DC pulsation egudileyo.

I-YMIN capacitors inezi mpawu zilandelayo kwi-inverter:

Izinto ezilungileyo zokuxinana komthamo ophezulu:

Ekupheleni kwegalelo le-micro-inverter, kuyimfuneko ukufumana amandla ombane avela kwisixhobo samandla avuselelekayo. Ezi ntlawulo kufuneka ziguqulwe yi-inverter ngexesha elifutshane.
