Kufotokozera kwapamwamba kwa mphamvu yamagetsi ya ng’anjo yosungunuka

Kufotokozera kwapamwamba kwambiri kwa mphamvu ya ng’anjo yosungunula yosungunula: Mumayendedwe olemetsa, nsonga yapamwamba ya mawonekedwe apano amachitika pambuyo pa nsonga yamphamvu yamagetsi. Kupatukana kwa nsonga za ma waveform awiriwa kumatha kuwonetsedwa ndi mphamvu yamagetsi. Kutsika kwa mphamvu yamagetsi, kumapangitsanso kusiyana pakati pa nsonga ziwiri za mafunde. Paulkin atha kubweretsanso nsonga ziwirizo molumikizananso, potero kuwongolera magwiridwe antchito.

Mphamvu yamagetsi ndi imodzi mwama data ofunikira a mabwalo a AC. Mlingo wa mphamvu yamagetsi ndi wofunikira kwambiri pakugwiritsa ntchito ndi kusanthula ng’anjo zosungunula zamagetsi, komanso kuphunzira kugwiritsa ntchito mphamvu zamagetsi ndi zina. Zomwe zimatchedwa mphamvu zimatanthawuza cosine wa kusiyana kwa gawo pakati pa voteji U pa malekezero onse a maukonde awiri-omaliza (wozungulira ndi kulankhula awiri kwa dziko lakunja) ndi panopa ine mmenemo. Mphamvu yogwiritsidwa ntchito pamanetiweki amitundu iwiri imatanthawuza mphamvu yapakati, yomwe imatchedwanso mphamvu yogwira ntchito, yomwe ili yofanana ndi: P=UIcosΦ. Kuchokera pa izi, zikhoza kuwoneka kuti mphamvu P yomwe ikugwiritsidwa ntchito pozungulira imadalira osati pa voliyumu V ndi panopa I, koma imagwirizananso ndi mphamvu. Mphamvu yamagetsi imadalira chikhalidwe cha katundu mu dera. Kwa katundu wotsutsa, kusiyana kwa gawo pakati pa magetsi ndi apano ndi 0, kotero mphamvu yamagetsi ndiyo yaikulu kwambiri (); pomwe pamabwalo oyendera bwino, kusiyana kwa gawo pakati pa magetsi ndi apano ndi π/2, ndipo voteji imatsogolera pakalipano; mu capacitance koyera Pozungulira, kusiyana kwa gawo pakati pa magetsi ndi magetsi ndi-(π/2), ndiko kuti, magetsi amatsogolera magetsi. M’mabwalo awiri omaliza, mphamvu yamagetsi ndi ziro. Kwa mabwalo amtundu wamba, mphamvu yamagetsi ili pakati pa 0 ndi 1.
