GEAR TO SUPPLY LOAD WITH DIRECT CURRENT Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: gear to supply load with direct current has principal source and booster with taps. LCD cell is terminated at taps of booster through voltage control unit and keys. In starting state load is fed with summary voltage of principal source and booster. With increase of current consumption LCD cell is connected to one tap of booster through key by signal from control unit. Power is being accumulated in choke of cell which is sent into load through capacitor of cell. EFFECT: enhanced reliability of operation in independent power supply systems with electrochemical power supply source. 2 cl, 1 dwg
