1. Malinga ndi tebulo logawanitsa lopangidwa ndi Institute of Electrical and Electronics Engineers (IEEE), mafupipafupi otsika ndi 30 ~ 300kHz, ma frequency apakati ndi 300 ~ 3000kHz, ma frequency apamwamba ndi 3 ~ 30MHz, ndipo ma frequency osiyanasiyana a 30 ~ 300MHz ndiokwera kwambiri. , 300~ 1000MHz ndi ma frequency apamwamba kwambiri. Poyerekeza ndi ma sign afupipafupi, zizindikiro zapamwamba zimasintha mofulumira kwambiri ndipo zimakhala ndi kusintha kwadzidzidzi; zizindikiro zotsika zimasintha pang'onopang'ono ndipo zimakhala ndi mawonekedwe osalala.

2. Mphamvu zamagetsi ndi chizindikiro ndizosiyana. Magetsi operekedwa ndi gulu lamagetsi nthawi zambiri amakhala ndi pafupipafupi 0 (DC magetsi) kapena 50hz (Mphamvu ya AC). Chizindikirocho chikhoza kunenedwa kuti ndi maulendo apamwamba kapena otsika kwambiri (kapena ma frequency ena). Ndizovuta kunena ngati bolodi lamagetsi likugwiritsidwa ntchito popangira magetsi, chifukwa amangogwiritsidwa ntchito popereka mphamvu ndipo mafupipafupi ndi otsika kwambiri. Ngati izo ziyenera kunenedwa, ndi pafupipafupi otsika.

3. Ubwino waukulu wa ma inverters apamwamba kwambiri ndi kulemera kopepuka, kukula kochepa, otsika standby mphamvu, komanso kuchita bwino kwambiri (kupulumutsa mphamvu zina). Choyipa ndichakuti kukana kwamphamvu sikuli bwino ngati inverter yamagetsi yamagetsi (kuti, kutsika kwafupipafupi komwe mwatchula), ndipo mwina sichingathe kunyamula zida zamagetsi monga zosakaniza zakudya ndi zoboolera pamanja. Zoyipa za ma frequency otsika ndikuti ndizolemera komanso zazikulu, mtengo ukhoza kukhala wokwerapo pang'ono, ndipo kutayika kwake kudzakhala kwakukulu pang'ono (imawononga pang'ono magetsi). Ubwino wake ndi woti ndi yolimba komanso imatha kunyamula zida zamagetsi zamagetsi.
