Musiyano pakati pe-single-phase inverter uye matatu-phase inverter

1. Single-phase inverter

Imwe-phase inverter inoshandura iyo DC inopinza kuita imwe-chikamu chinobuda.Iyo inobuda voltage / ikozvino yeimwe-chikamu inverter inongova chikamu chimwe chete, uye yayo yezita frequency ndeye 50HZ kana 60Hz zita remagetsi.Iro zita remagetsi rinotsanangurwa seyero yevoltage inoshandiswa nemagetsi.Kune akasiyana nominal voltages, kureva 120V, 220V, 440V, 690V, 3.3KV, 6.6KV, 11kV, 33kV, 66kV, 132kV, 220kV, 400kV, uye 765kV kufambisa nhamba idzi: , Ndiyo 11kV, 22kV, 66kV, nezvimwewo?

Low nominal voltages inogona kuwanikwa yakananga kuburikidza neinverter uchishandisa yemukati transformer kana nhanho-up booster circuit, nepo kune yakakwira nominal voltages yekunze booster transformer inoshandiswa.

Single-phase inverters inoshandiswa kune yakaderera mitoro.Kuenzaniswa neyechitatu-phase inverter, iyo imwe-chikamu kurasikirwa yakakura uye kugona kwakaderera.Nokudaro, matatu-phase inverters inosarudzwa nokuda kwemitoro yakakwirira.

2. Nhatu-phase inverter

Matatu-phase inverters anoshandura DC kuita matatu-chikamu simba.Iwo matatu-chikamu magetsi anopa matatu anochinjana ikozvino nemakona akapatsanurwa chikamu.Ese mafungu matatu anogadzirwa pamagumo ekubuda ane amplitude akafanana uye frequency, asi akasiyana zvishoma nekuda kwekuremerwa, nepo wave imwe neimwe ine 120o phase shift pakati peumwe neumwe.

Chaizvoizvo, imwe yetatu-phase inverter ndeye 3 single-phase inverter, apo yega yega inverter iri 120 madhigirii kunze kwechikamu, uye yega yega-chikamu inverter yakabatana kune imwe yetatu mitoro terminals.

Zvemukati Bhurawuza: Chii chinonzi matatu-chikamu inverter, chii basa

Kune akasiyana matopology ekuvaka matatu-chikamu voltage inverter maseketi.Kana iri bhiriji inverter, ichimhanyisa switch mu 120 dhigirii modhi kushanda kweyechitatu-chikamu inverter kunoita kuti switch yega yega ishande kwenguva yakazara yeT/6, iyo inoburitsa yakabuda waveform ine nhanho nhanhatu.Pane zero voltage nhanho pakati peiyo yakanaka uye yakaipa voltage mazinga eiyo square wave.

Iyo inverter simba rating inogona kuwedzera kuwedzera.Kuti ugadzire inverter ine simba repamusoro, 2 inverters (matatu-phase inverters) akabatanidzwa mumutsara kuti awane chiyero chepamusoro.Kune yakakwirira ikozvino ratings, 2 6-nhanho 3 inverters inogona kubatanidzwa.
