Kab lus no qhia txog qhov tshwj xeeb thiab muaj teeb meem txoj hauv kev los tsim LED teeb duab teeb duab.

Lub voj voog no xav tau lub siab AC lub teeb liab siab. Koj tuaj yeem sim txuas Class D amplifier.

Lub voj voog no tau tsim thiab luam tawm ntau xyoo dhau los raws li kab lus pom ntawm no:

Simulations qhia qhov tso tawm tam sim no qis rau LEDs. Qhov no yuav tsis muaj tseeb hauv lub neej tiag tiag yog tias koj siv lub zog loj transistor. Lub zog hluav taws xob qis muaj qhov txwv tsawg tshaj plaws tam sim no tso tawm.

Kauj Ruam 3: Ua Circuit Court

Koj tuaj yeem pom tias kuv tau ua qhov Circuit Court no ntawm ib daim duab los kom txuag tau nyiaj. Kuv tuaj yeem siv daim yas, ntoo, lossis txawm tias yog pawg thawj coj saib.

Kuv siv qis tam sim no, me me 5 mA LEDs, thiab lub zog tiv taus siab. Kuv kuj siv lub zog loj transistor thiab lub rhaub dej kub.

Kauj ruam 4: Xeem

Qhov kev sim qhia pom tias qhov sib txawv ntawm qhov sib txawv resistor teeb tsa hloov tus lej ntawm LEDs uas tau qhib rau.
