Ha theknoloji e ntse e hatela pele, tlhoko ea lisebelisoa tsa elektroniki e ntse e eketseha. Ho fihlela litlhoko tsena, phepelo e phahameng ea maqhubu a DC e fetohile theknoloji ea bohlokoa. Ho tloha ho lisebelisoa tsa mehala ea puisano ho ea ho lisebelisoa tsa bongaka, ho tloha taolong ea indasteri ho ea ho lisebelisoa tsa elektroniki tsa motho,high frequency switching DC phepelo ea motlakasee kenelletse karolong e 'ngoe le e 'ngoe ea bophelo ba rona.
