Sine wave inverter magetsi

1. Mbali zazikulu za magetsi a sine wave inverter
■ Pogwiritsa ntchito CPU control, dera ndi losavuta komanso lodalirika;
■ Pogwiritsa ntchito ukadaulo wa SPWM pulse wide modulation, cholowetsacho ndi mafunde oyera a sine okhala ndi ma frequency okhazikika komanso kuwongolera ma voltage, kusefa phokoso ndi kusokoneza pang'ono;
■ Kusintha kolowera mkati, kusinthana mwachangu pakati pa mains ndi inverter;
■ Mtundu waukulu wamagetsi ndi mtundu waukulu wa batri:
A) Mtundu wamagetsi a mains: pakakhala mphamvu ya mains, imakhala yotulutsa mains, ndipo imasinthiratu kutulutsa kwa inverter pomwe kulowetsa kwa mains kulephera;
B) Mtundu waukulu wa batire: Kutulutsa kwa inverter pakakhala mphamvu ya mains, yodziwikiratu pomwe kulowetsa kwa DC kwalephera
■ kusintha kwa mains linanena bungwe;
Zimaloledwa kudula DC m'malo opangira mphamvu, ndikusinthira ku mains bypass, osakhudza mphamvu ya katunduyo, ndipo ndikosavuta kusamalira ndikusintha batire;
■ Ngati mphamvu ya batri ndiyokwera kwambiri kapena yotsika kwambiri, mphamvu ya inverter idzazimitsa zomwe zimachokera.Ngati mphamvu ya batri ikubwerera mwakale, mphamvu yamagetsi idzatuluka yokha;
■ Pamene katundu wodzaza, mphamvu ya inverter idzazimitsa zotuluka.Pambuyo pa masekondi a 50 kuchotsa zochulukira, magetsi adzayambiranso kutulutsa.Ntchitoyi ndiyoyenera makamaka kwa malo olumikizirana osayang'aniridwa;
■ Ntchito yolumikizirana yothandizira, perekani mawonekedwe a RS232 (PIN2, 3, 5), gwiritsani ntchito pulogalamu yowunikira kuti mumvetsetse momwe magetsi amagwirira ntchito munthawi yeniyeni;(Dziwani: Mitundu ya 500VA pamndandandawu ilibe ntchitoyi pakadali pano)
■ Perekani ma seti awiri a ma node owuma a DC input fault (RS232PIN6, 7) ndi AC output fault alarm (RS232PIN8, 9)
■ Imathandiza opanda DC mphamvu pa ntchito, ndipo akhoza kuthamanga ndi mains mphamvu kokha.Ntchitoyi imalola kuti magetsi a inverter ayambe kugwiritsidwa ntchito, ndiyeno batire imayikidwa.(Dziwani: Mitundu ya 500VA pamndandandawu ilibe ntchitoyi pakadali pano)
