Umhlinzeki weyunithi ye-frequency converter braking ukukhumbuza ukuthi ubuchwepheshe bokulawula isivinini sokuguqula imvamisa busetshenziswe kabanzi emkhakheni wezimboni. Ezisetshenziswa eziningi zokulawulwa kwesivinini esishintshashintshayo, amandla okuvuselela ngokuvamile akhiqizwa. Njengamanje, izindlela eziningi zokuphatha amandla okuvuselela akhiqizwa ngesikhathi senqubo yokulawula isivinini esishintshashintshayo ukusebenzisa amayunithi okubhuleka adla amandla - okungukuthi, ngokufaka ama-resistors amabhuleki anamandla amakhulu kanye nokusebenzisa la mandla ngokushisisa ama-braking resistors. Ukusetshenziswa kwamayunithi okubhuleka adla amandla ukucubungula amandla okuvuselela kuzodla inani elikhulu lamandla kagesi ngeze, futhi kukhiphe ngisho nokushisa okukhulu, kungcolise indawo yokusebenza yemishini kagesi futhi kunciphise kakhulu impilo yayo yesevisi.
Isistimu yempendulo yamandla ye-PSG ingena esikhundleni sendlela yokumelana nebhuleki ngobuchwepheshe bempendulo yamandla, eguqula amandla avuselelwe akhiqizwa phakathi nenqubo yokulawula isivinini esishintshashintshayo ibe amandla kagesi ahlanzekile ngokuguquguquka nokucutshungulwa kwe-harmonic, futhi iwafunze iwabuyisele kugridi yamandla ukuze isetshenziswe izisetshenziswa zikagesi ezizungezile. Ukushintsha ibhuleki yokumelana nempendulo ye-PSG yamandla kungaletha izinzuzo eziningi:
1. Ukwengeza impendulo ye-PSG yamandla kungaqeda ngokushesha i-voltage yokumpompa yesiguquli sefrikhwensi, kuthuthukise kakhulu ukusebenza kahle kwamabhuleki;
2. Umthelela wokonga amandla wempendulo ye-PSG yamandla ubaluleke kakhulu, ngenani elibanzi lokonga amandla phakathi kuka-20% no-60%;
3. Ngaphandle kwezinto zokushisisa ezinamandla amakhulu, izinga lokushisa ekamelweni lekhompyutha liyehla, ukonga ugesi emishinini yokupholisa efana ne-air conditioning, ukuzuza imiphumela engcono yokonga amandla;
Ngaphandle kwezinto zokushisa zamandla aphezulu, kulingana nokuqeda ingozi yokuphepha eduze kwegumbi lekhompyutha noma okokusebenza;
