Lub sijhawm no nws yog ib theem-sine yoj tawm ntawm daim phiaj tswj hwm, ua raws los ntawm ib-theem sine yoj tawm ntawm daim phiaj tswj hwm, tom qab ntawd peb-theem sine yoj tawm ntawm daim phiaj tswj hwm, thiab thaum kawg peb-theem sine yoj tawm-daim phiaj tswj hwm pawg thawj coj saib. Peb vam tias txhua tus yuav txhawb nqa nws. Txhua qhov kev daws teeb meem siv PIC microcontrollers.

Cia kuv tham txog kuv lub hom phiaj hauv kev ua kab sib chaws sib txuas inverter. Kuv xav kom ua tiav txoj haujlwm ntawm "tawm tswv yim hluav taws xob thauj khoom". Vim tias cov neeg laus hloov pauv lossis laus hloov cov khoom siv hluav taws xob, txhua tus siv cov khoom tiv thaiv raws li kev thauj khoom thiab pov tseg lub zog. Kuv xav tias yuav sau cov hluav taws xob no thiab pub nws mus rau qhov kawg ntawm peb cov khoom siv hluav taws xob hauv daim ntawv ntawm kev siv hluav taws xob sib txuas sib txuas. Qhov no tsim cov khoom lag luam laus. Raws li txoj cai, cov khoom siv hluav taws xob tag nrho tsis siv hluav taws xob. Qhov tseeb, poob ntawm cov tshuab thiab khoom siv yuav tsum tau ntxiv, yog li cov lus tawm tswv yim hluav taws xob thauj khoom tuaj yeem sau 90% ntawm lub zog hluav taws xob. Nov yog kuv lub hom phiaj, thiab peb tseem xav tau koj kev txhawb nqa! Yog tias koj xav ua daim phiaj txuas nrog inverter, koj yuav tsum ua qhov zoo tawm ntawm daim phiaj inverter. Tsis hais ntau, ua ntej saib ntawm daim duab schematic ntawm ib-theem tawm-daim phiaj sine yoj tswj hwm pawg thawj coj saib.

Pawg tswj hwm no tau tsim tshwj xeeb los tsav IGBTs lub zog loj. Nws muaj qhov tsis zoo kaw qhov haujlwm thiab yog qhov kev xaiv zoo tshaj plaws rau IGBTs. Sab laug yog H-choj tsav lub zog muab, nruab nrab sab saud yog lub hauv paus ntawm lub microcontroller, nruab nrab qis yog H-choj inductive tso zis tam sim no sib piv, uas tswj lub zog tso tawm, thiab sab xis yog IGBT tsav ceev optocoupler, uas tshwj xeeb tsav IGBT thiab muab qhov tsis zoo kaw qhov tshwj xeeb. Txhua leej txhua tus paub tias FETs tuaj yeem tua thiab tua ntawm qhov hluav taws xob qis, thiab IGBTs tsis zoo ib yam. Yuav tsum muaj qhov hluav taws xob tsis zoo kom ntseeg tau tua tau.

Tom ntej no, kos PCB. Kuv ntseeg tias txhua tus neeg paub txog sine wave off-grid. Kuv tsis piav ntau. Kuv yuav muab cov lus piav ntxaws ntxaws rau ntawm kab sib txuas. Kuv kuj siv cov nti no PIC16F716 rau daim phiaj Sine wave tswj lub rooj tsavxwm

Kuv tau xa kuv tus PCB tsim mus rau Stariver Circuit kom ua PCB tus qauv thiab sib dhos, tus paub PCB tsim khoom hauv Suav teb. Lawv cov khoom lag luam zoo thiab muaj tus nqi tsim nyog.

Ua ntej, 14 tus pin thiab 15 tus lej nkag 24V DC zog. Kuaj 6 thiab 8 tus pin ntawm txhua tus optocoupler nrog qhov hluav taws xob ntawm 24V. Tom qab ntawd nkag 5V ntawm 16 tus pin, thiab oscilloscope kuaj 5 thiab 8 tus pin. 10 ko taw thiab 12 ko taw, cov zis yog 16KHz ntxiv SPWM yoj, koj ua tiav!

Dhau li, vim li cas kuv thiaj yuav tsum sau tus neeg nqa khoom ntau ntawm 16KHz, vim tias tus neeg nqa khoom zaus ntawm 16KHz tuaj yeem hloov kho rau IGBT qhov muaj zog ntau ntawm cov qauv, tsuas yog tus qauv IGBT tuaj yeem ua lub zog hluav taws xob zoo sine wave inverter. Kuv xav siv cov tshuaj no thaum kuv muaj sijhawm. Ua 20KW ib-theem sine wave inverter.

Qhov kev ntsuas no tau ua tiav, qhov zaus tso tawm yog qhov tseeb, qhov hluav taws xob tso tawm ruaj khov yog qhov zoo heev, thiab lub zog thauj khoom thiab tsis muaj qhov tso tawm qhov hluav taws xob tseem tsis hloov pauv.

Qhov piv txwv software qhov kev ruaj ntseg hom txais yuav cov qauv ntawm qhov siab tshaj qhov ruaj khov, qhov hluav taws xob muaj txiaj ntsig tam sim tawm tswv yim thiab cov txiaj ntsig muaj txiaj ntsig zoo, thiab ob npaug kaw lub voj tswj. Sab nraum lub voj voos hluav taws xob rms tawm tswv yim ua rau lub kaw lus ruaj khov li sai tau yam tsis muaj qhov tso zis zoo li qub. Lub voj sab hauv siv kev tawm tswv yim tam sim kom ntseeg tau tias lub kaw lus tau txais txiaj ntsig zoo tshaj plaws. Ob leeg ua lawv txoj haujlwm thiab ua haujlwm ua ke.
