Muindasitiri yemagetsi uye otomatiki, kushandiswa kweMOSFETs(metal-oxide-semiconductor field-effect transistors) yava chinhu chinokosha pakuvandudza kushanda kwemagetsi ekumhanya kwemagetsi (ESR). Chinyorwa ichi chinoongorora mashandiro anoita maMOSFET uye nemabatiro avanoita basa rakakosha mumagetsi ekumhanya kudzora.
Iyo yakakosha kushanda musimboti weMOSFET:
A MOSFET chishandiso chesemiconductor chinoshandura kuyerera kwemagetsi ikozvino kana kudzima kuburikidza nemagetsi ekudzora. Mumagetsi ekumhanya maregulators, maMOSFET anoshandiswa sekuchinja zvinhu kudzora kuyerera kwazvino kuenda kumota, zvichibvumira kutonga chaiko kwekumhanya kwemota.
Zvishandiso zveMOSFET mune zvemagetsi kumhanya regulators:
Kutora mukana weiyo yakanakisa yekuchinja kumhanya uye inoshanda ikozvino kudzora masimba, MOSFETs anoshandiswa zvakanyanya mumagetsi ekumhanya maregi muPWM (Pulse Width Modulation) maseketi. Ichi chishandiso chinovimbisa kuti mota inogona kushanda zvakatsiga uye nemazvo pasi pemamiriro akasiyana emutoro.
Sarudza iyo MOSFET yakakodzera:
Paunenge uchigadzira yemagetsi kumhanya regulator, kusarudza iyo chaiyo MOSFET yakakosha. Maparamendi ekufunga nezvawo anosanganisira yakanyanya drain-source voltage (V_DS), yakanyanya kuenderera inodonha yazvino (I_D), switching speed, uye thermal performance.
Aya anotevera ndiwo nhamba dzechikamu chekunyorera cheWINSOK MOSFETs mune zvemagetsi kumhanya regulators:
