Kwiintlobo ze-inverter kunye nomahluko

Ngokuxhomekeke kwiimfuno zakho ezithile kunye neemfuno zakho, ungakhetha kwiintlobo ngeentlobo zee-inverters. Ezi ziquka i-square wave, i-modified square wave, kunye ne-pure sine wave inverter. Zonke ziguqula amandla ombane avela kumthombo we-DC abe yi-alternating current, esetyenziswa zizixhobo. I-inverter ingahlengahlengiswa ukuvelisa i-voltage oyifunayo.

Ukuba unomdla wokuthenga i-inverter entsha, kufuneka ubale ukusetyenziswa kwamandla okupheleleyo kwezixhobo zakho. Umlinganiselo wamandla opheleleyo we-inverter uchaza ukuba isixhobo sinokubonelela ngamandla angakanani kumthwalo. Oku kudla ngokubonakaliswa ngee-watts okanye ii-kilowatts. Ungafumana ne-inverter enomlinganiselo ophezulu wamandla aphezulu, kodwa oku kudla ngokubiza kakhulu.

Enye yezona ntlobo zisisiseko zee-inverters, i-square wave inverter, iguqula umthombo we-DC ube yi-square wave AC output. Le wave iphantsi kakhulu kwi-voltage kunye ne-current, nto leyo eyenza ukuba ilungele ukusetyenziswa kwe-low sensitivity. Ikwaluhlobo lwe-inverter olungabizi kakhulu. Nangona kunjalo, le waveform inokudala isandi "sokucula" xa iqhagamshelwe kwizixhobo ze-audio. Ayifanelekanga kakuhle kwi-electronics ezinobuthathaka kunye nezinye izixhobo.

Uhlobo lwesibini lwe-inverter, i-modified square wave, iguqula umthombo we-DC ube yi-alternating current. Isebenza ngcono kune-square wave, kodwa ayigudi kangako. Olu hlobo lwe-inverter lungathatha imizuzu eliqela ukuqala ukusebenza. Ayilulo ukhetho olufanelekileyo kwizixhobo ezifuna ukuqaliswa ngokukhawuleza. Ukongeza, i-THD factor (total harmonic distortion) ye-wave inokuba phezulu, nto leyo eyenza kube nzima kwizicelo ezithile. I-wave ingatshintshwa ukuze ivelise i-pulsed okanye i-modified sine wave.

Ii-inverters zinokuyilwa ngeendidi ezahlukeneyo zee-power circuit topology, nganye ijongana nemiba eyahlukeneyo. Ii-inverters zingasetyenziselwa ukuvelisa amaza e-sine aguquliweyo, amaza esikwere ashukunyisiweyo okanye aguquliweyo, okanye amaza e-sine amsulwa. Ungakhetha ne-inverter etyalwe yi-voltage, eneempawu ze-buck-converter. Ezi ntlobo zee-inverters zihlala zincinci, zilula, kwaye zibiza kancinci kunee-inverters ezisekelwe kwi-transformer.

Ii-inverters zinokukhetha ukusebenzisa isekethe ye-thyristor. Isekethe ye-thyristor ilawulwa yi-commutation capacitor, elawula ukuhamba kombane. Oku kuvumela ii-thyristors ukuba zinike amandla amakhulu okuphatha amandla. Kukwakho neesekethe ze-forced commutation ezinokongezwa kwi-SCRs.

Uhlobo lwesithathu lwe-inverter, i-inverter enamanqanaba amaninzi, inokuvelisa i-AC voltage ephezulu evela kwizixhobo ezikumgangatho ophantsi. Olu hlobo lwe-inverter lusebenzisa iintlobo ngeentlobo zee-topologies zesekethe ezahlukeneyo ukuze luphucule ilahleko zokutshintsha. Ingenziwa njengesekethe yochungechunge okanye ehambelanayo. Ingasetyenziswa nakwi-standby power supply ukuphelisa i-switchover transient.

Ngaphandle kweentlobo zee-inverters ezikhankanyiweyo apha ngasentla, ungasebenzisa i-inverter yokulawula i-motor ye-variable frequency ukuphucula i-waveform kunye nokukuvumela ukuba ulungise i-output voltage. Olu hlobo lwe-inverter lungasebenzisa neendlela ezahlukeneyo zokulawula ukuphucula ukusebenza kwe-inverter.de.
