Kuv thaum kawg txiav txim siab ntxiv lwm txoj kab rau kuv tus tswj kev them nyiaj thiab kuv xav tau lub zog ruaj khov hloov pauv PWM uas tawm los ntawm cov khoom pov tseg yog li kuv tau ua qhov yooj yim me me Circuit Court coj PWM teeb liab thiab hloov nws mus rau DC teeb liab tas li.

Txhawm rau tsim cov hauv paus hauv paus koj yuav xav tau:

  1. Ib MOSFET. Kuv siv IRF3205
  2. Ib lub capacitor
  3. Ob tug resistors
  4. Jumper xov hlau

Nws yog lub sijhawm tam sim no los ntsuas lub Circuit thiab ntxiv cov khoom ntxiv.

Ntxiv lub pob txuas rau txoj kev tsheb nqaj hlau zoo rau lub teeb liab hauv kab thiab txuas ib qho LED thiab tus tiv thaiv rau lub teeb liab tawm kab. Siv lub zog thiab thawb lub pob, yog tias nws teeb rau lub sijhawm luv ces ploj mus, lub Circuit Court ua haujlwm tau zoo thiab tam sim no koj tuaj yeem ntxiv qhov txuas ntxiv yog tias koj xaiv qhov ntawd. Txoj hauv kev ua haujlwm no yog thaum lub teeb liab nkag mus, kab nkag siab thiab tsub tus nqi hluav taws xob thiab qhib lub transistor. Lub resistor txuas nrog hauv av maj mam ntws cov capacitor ntawm nws lub nqi thiab thaum lub capacitor nce mus txog qee qhov hluav taws xob, transistor ploj mus thiab kaw. Dab tsi qhov kev xa tawm ua yog ua raws li hom quasi schmitt txhais thiab muab kev hloov pauv zoo los ntawm rau mus rau yam tsis ploj mus los ntawm kev ua txhaum kev sib cuag thaum cov zis los ntawm transistor tsoo qee qhov hluav taws xob. Qhov kev txiav txim no yuav siv tau rau kev siv cov khoom siv hluav taws xob uas tsis tuaj yeem tiv taus qhov nruab nrab ntawm qhov hluav taws xob tau zoo heev xws li lub tshuab nqus dej uas tau tsav (AC) lossis inverter (DC).
