Daim ntawv thov scenario:

1. Lub tsev me me hnub ci zog

2. Sab nraum zoov hnub ci zog

3. Portable hnub ci daim ntaub ntawv

Kev ua haujlwm siab MPPT lub tswv yim, kev siv lub hnub ci vaj huam sib luag yog 99 feem pua.

LCD thiab LED tso saib ntau yam tsis sib xws, xws li input voltage, roj teeb hom, roj teeb voltage, them tam sim no, them lub zog, ua haujlwm.

Lub Maximum Power Point Tracking (MPPT) hnub ci maub los tuaj yeem kuaj xyuas lub zog siab tshaj plaws ntawm lub hnub ci vaj huam sib luag hauv lub sijhawm, thiab taug qab qhov siab tshaj plaws voltage thiab tam sim no tus nqi (VI), kom lub kaw lus tuaj yeem them lub roj teeb nrog kev ua haujlwm siab tshaj plaws. Lub roj teeb them yog muab faib ua peb theem ntawm trickle tam sim no, siab tam sim no thiab tsis tu ncua voltage. Yog hais tias lub hwj chim input zoo tagnrho, thawj ob theem yog qhov tam sim no, thiab theem tom ntej yog qhov tsis tu ncua. Yog tias nws tsis zoo tagnrho, siv mppt los txhawb lub zog kom deb li deb tau kom ncav cuag qhov ntsuas tam sim no lossis qhov ntsuas hluav taws xob tas li. .

Tam sim no, lub tshuab hluav taws xob photovoltaic boosting thev naus laus zis nrog MPPT yog cov zis tom qab tau txhawb nqa los ntawm kev sib cais transformer. Txawm li cas los xij, qhov ntim ntawm kev sib cais transformer yog qhov loj, thiab cov windings yuav tsum tau muab qhwv nrog insulating kua nplaum. Tsis tas li ntawd, qhov sib cais transformer yuav tsim kom muaj cua sov ntau thaum lub sijhawm ua haujlwm, yog li nws muaj qhov xav tau ntau dua rau cov cua sov dissipation ntawm MPPT hnub ci maub los. Tsis tas li ntawd, qhov kev tiv thaiv hluav taws xob tiv thaiv rau lwm yam khoom siv hauv MPPT hnub ci maub los kuj siab.
