Hauv kev lag luam electronics thiab automation, daim ntawv thov ntawmMOSFETs(hlau-oxide-semiconductor field-effect transistors) tau dhau los ua qhov tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm hluav taws xob ceev regulators (ESR). Kab lus no yuav tshawb xyuas seb MOSFETs ua haujlwm li cas thiab lawv ua lub luag haujlwm tseem ceeb hauv kev tswj hluav taws xob ceev.
Lub hauv paus ntsiab lus ua haujlwm ntawm MOSFET:
MOSFET yog cov khoom siv hluav taws xob semiconductor uas hloov qhov ntws ntawm hluav taws xob tam sim no rau lossis tawm los ntawm kev tswj hluav taws xob. Nyob rau hauv hluav taws xob ceev regulators, MOSFETs yog siv los hloov cov ntsiab lus los tswj cov dej ntws tam sim no rau lub cev muaj zog, uas tso cai rau kev tswj xyuas qhov ceev ntawm lub cev muaj zog.
Kev siv MOSFETs hauv hluav taws xob ceev regulators:
Ua kom zoo dua ntawm nws qhov kev hloov pauv zoo heev thiab muaj peev xwm tswj tau tam sim no, MOSFETs tau siv dav hauv hluav taws xob ceev tswj hauv PWM (Pulse Width Modulation) circuits. Daim ntawv thov no ua kom ntseeg tau tias lub cev muaj zog tuaj yeem ua haujlwm ruaj khov thiab ua haujlwm zoo nyob rau hauv ntau yam kev thauj khoom.
Xaiv txoj cai MOSFET:
Thaum tsim lub tshuab hluav taws xob ceev, xaiv txoj cai MOSFET yog qhov tseem ceeb. Cov kev ntsuas uas yuav tsum tau txiav txim siab suav nrog qhov siab tshaj qhov ntws tawm qhov hluav taws xob (V_DS), qhov siab tshaj plaws txuas txuas tam sim no (I_D), kev hloov ceev, thiab kev ua haujlwm thermal.
