Lub hnub ci inverter yog cais raws li cov zis waveform

(1) Square wave inverter

AC voltage waveform tso zis los ntawm square wave inverter yog square yoj. Lub inverter circuits siv los ntawm xws li inverters tsis zoo ib yam, tab sis qhov zoo tshaj plaws yog tias lub Circuit Court yog qhov yooj yim thiab tus naj npawb ntawm cov hluav taws xob hloov hluav taws xob siv me me. Lub zog tsim yog feem ntau ntawm 100W thiab kW. Qhov zoo ntawm square yoj inverter yog yooj yim Circuit Court, tsis tshua muaj nqi thiab yooj yim txij nkawm. Qhov tsis zoo yog tias qhov square yoj voltage muaj ntau qhov kev txiav txim siab siab, uas yuav ua rau poob ntxiv hauv cov khoom siv hluav taws xob thauj khoom nrog cov tub ntxhais hlau inductors lossis transformers, thiab cuam tshuam nrog cov xov tooj cua thiab qee cov khoom siv sib txuas lus. Tsis tas li ntawd, hom inverter no muaj qee qhov tsis txaus, xws li kev tswj hwm qhov hluav taws xob tsis txaus, kev tiv thaiv tsis txaus, thiab lub suab nrov.

(2) Stepped yoj inverter

Lub AC voltage waveform tso zis los ntawm xws li inverter yog kauj ruam yoj, thiab muaj ntau ntau cov kab sib txawv rau inverter kom paub cov kauj ruam yoj zis, thiab tus naj npawb ntawm cov kauj ruam ntawm cov zis waveform txawv heev. Qhov zoo ntawm cov kauj ruam yoj inverter yog tias cov zis waveform yog qhov zoo dua piv nrog cov square nthwv dej, thiab cov ntsiab lus ntawm kev sib haum xeeb siab dua yog txo. Thaum tus naj npawb ntawm cov kauj ruam mus txog ntau tshaj 17, cov zis waveform tuaj yeem paub txog quasi sine yoj. Thaum lub tshuab hluav taws xob tsis pub tso tawm tau txais yuav, qhov kev ua haujlwm tag nrho yog siab heev. Qhov tsis zoo yog tias muaj ntau lub zog hloov pauv siv nyob rau hauv cov kauj ruam yoj superposition kab, thiab qee cov kab xav tau ntau pawg ntawm DC lub zog nkag. Qhov no ua rau muaj teeb meem rau kev sib koom ua ke thiab xaim ntawm lub hnub ci cell arrays thiab sib npaug ntawm kev them cov roj teeb. Tsis tas li ntawd, cov kauj ruam yoj voltage tseem muaj qee qhov kev cuam tshuam loj ntawm cov xov tooj cua thiab qee cov khoom siv sib txuas lus.

(3) Sine wave inverter

AC voltage waveform tso zis los ntawm sine yoj inverter yog sine yoj. Qhov zoo ntawm sine yoj inverter yog qhov zoo tso tawm waveform, tsis tshua muaj kev cuam tshuam, cuam tshuam rau xov tooj cua thiab khoom siv, thiab suab nrov tsawg. Tsis tas li ntawd, kev tiv thaiv kev ua haujlwm tiav thiab kev ua haujlwm tag nrho yog siab. Disadvantages: Lub Circuit Court yog qhov nyuaj, yuav tsum tau siv tshuab ua haujlwm siab thiab kim heev.

Kev faib tawm ntawm peb hom inverters saum toj no yog qhov tsim nyog rau kev txheeb xyuas thiab kev xaiv ntawm inverters los ntawm cov neeg tsim qauv thiab cov neeg siv cov tshuab photovoltaic thiab cua tshuab tsim hluav taws xob. Qhov tseeb, inverters nrog tib lub waveform tseem muaj qhov sib txawv ntawm cov qauv hauv Circuit Court, cov cuab yeej siv thiab kev tswj xyuas.
