SUPPLY UNIT FOR CAPACITANCE LOAD Russian patent published in 2011 - IPC H02M7/5381 C01B13/11 

FIELD: electricity.

SUBSTANCE: block comprises a transformer, a generator of positive half-cycles and a generator of negative half-cycles, which supply both positive and negative voltage half-cycles to the first coil. The second coil generates an electric resonant circuit and sends electric energy to a load. Transitions via a voltage zero sent to the first coil are detected starting from the third coil on the transformer, and alternation of positive and negative voltage half-cycles sent to the first coil is carried out when the voltage supplied to the first coil is passed via zero.

EFFECT: improved reliability and reduced consumption of resources.
