FEED CIRCUIT AND DEVICE CONTAINING FEED CIRCUIT Russian patent published in 2011 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: feed circuits (1-3, 101-102, 201-203) for supply of output current signals to loads (6, 106, 206) and containing the first circuits (1, 101, 201) with transistors (11-14, 111-112, 211-212) for conversion of input voltage signals to pulse signals and containing the second circuits (2, 102, 202) with resonant circuits to receive pulse signals and to supply output current signals to loads (6, 106, 206) are provided with the third circuits (3, 203) to control the first circuits (1, 101, 201); at that, the third circuits (3, 203) contain generators (35-37) for generation of control signals to control transistors (11-14, 111-112, 211-212) in order to reduce the dependence between input voltage signals and output current signals. The third circuits (3, 203) feed control signals depending on input voltage signals and irrespective of output current signals. Transistors (11-14, 111-112, 211-212) can form full bridge operating in half-bridge mode, or half-bridge.

EFFECT: supply of constant signal to load.
