Inverter ni iki?

Inverter ni DC kuri AC irahindura, mubyukuri nuburyo bwo guhinduranya voltage hamwe numwuka. Guhindura Guhindura AC voltage ya AC ya grid ihamye 12v DC ihagaze neza, mugihe uhindagurika voltage ya 12V dC hamwe na adaptor mumikino myinshi-voltage ac; Ibice byombi nabyo bikoresha byinshi bikunze gukoreshwa module (PWM) ikoranabuhanga. Igice cyibanze ni umugenzuzi wa PWM urimo, adapter ikoresha UC3842, kandi inverver ikoresha chip ya TL5001. Umukoresha wa TL5001 ni 3.6 ~ 40V, kandi ifite ikosa, umuyobozi wa PWM hamwe nigenzura rya voltage hamwe numuzunguruko muto wo kurinda voltage hamwe numuzunguruko mugufi.

Imigaragarire yinjiza igice: Igice cyinjiza gifite ibimenyetso 3, 12v DC yinjiza VIN, gukora bishoboza voltage enb na panel igenzura ryibimenyetso. Vin itangwa na adapt, kandi voltage ya enb itangwa na MCU ku kibaho, kandi agaciro kayo ni 0 cyangwa 3V. Iyo enb = 0, inverter ntabwo ikora, kandi iyo enb = 3V, inverter iri muri leta isanzwe; Kandi voltage ya dim itangwa na interineti, kandi urwego rwimyitwarire rwarwo ruri hagati ya 0 na 5v. Indangagaciro zitandukanye zigaburirwa ibisubizo byibitekerezo bya PWM umugenzuzi, kandi ubu byatanzwe nitsinda ryumutwaro nabyo bizaba bitandukanye. Gitoya agaciro gakomeye, ibirenzeho bisohoka muri inverter.

Voltage gutangira loop: Iyo enb ari ndende, voltage ndende ni umusaruro kugirango umurikire umuyoboro wamaguru winama.

Umugenzuzi wa PWM: Igizwe n'imikorere ikurikira: Imbere Yimbere, Ikosa Amplifier, OsiLillator na PWM, kurengera byinshi, kurinda ibintu bitunguranye, kurinda umutego.

DC Ihinduka: Umuzunguruko wo guhindura voltage ugizwe na mos hindura intera ya tube hamwe nububiko bwingufu. Iyinjiza yinjira irakorozwa no gukurura amplifier kandi itwara miss tube yo gukora guhinduranya ibikorwa, kugirango amafaranga ya DC aregwa kandi asohore innguramu, kugirango undi murambe wa InDuctor ashobore kubona ac voltage ac.

LC OSCALLAL N'IKIMENYETSO CY'UMUZIKI: Menya neza ko voltage ya 1600V isabwa ku itara ryo gutangira, kandi ugabanye voltage kuri 800v nyuma yitara ritangira.

Ibisohoka ibitekerezo bya voltage: Iyo umutwaro ukora, vopiseling voltage yahagaritswe kugirango ihuze na voltage ibisohoka muri nderter.

Imikorere
Inverter ihindura DC Power (bateri, bateri yububiko) mu mbaraga za AC (muri rusange 220v50hz Sine cyangwa kare wa kare). Mu magambo ya Layman, inverter nigikoresho gihindura kinyurane (DC) muburyo bundi (AC). Igizwe nikiraro cyinzoka, kugenzura logique noyunguruzo.
Muri make, inverter nigikoresho cya elegitoronike gihindura-voltage-voltage. Kubera ko 220 lublits AC ishingiye ku mbaraga za DC mu buryo bwo gukoresha, kandi uruhare rwa inverter ni ibinyuranye, bityo izina. Mugihe cy '"kugenda", ibiro bigendanwa, itumanaho rya terefone, imyidagaduro igendanwa n'imyidagaduro. Iyo bimukiye, ntabwo ari voltage yo hasi gusa birakenewe muri bateri cyangwa bateri yo kubika, ariko nanone 220-volt yo guhinduranya ububi, ningirakamaro mubuzima bwa buri munsi. Ababohembe barashobora kuzuza ibyo bakeneye.
