SINGLE-PHASE BRIDGE SELF-COMMUTATED VOLTAGE INVERTER (VERSIONS) Russian patent published in 2011 - IPC H02M7/53846 

FIELD: electricity.

SUBSTANCE: as per the first version, clock-pulse generator with two antiphase outputs is introduced to the device; each of the above outputs is connected to starting inputs of the first and the second shapers of control pulses of the appropriate control channel with output pulses of various duration. As per the second version, in the device there is the possibility of controlling output voltage of single-phase bridge SVI at simplified scheme and improved reliability of the device as a whole owing to the second shapers of control pulses of each switch control channel with two inputs - starting and control ones, owing to introduction of clock-pulse generator with two antiphase outputs, each of which is connected to starting inputs of the first and the second shapers of the appropriate channel with output pulses of various duration, as well as owing to introduction of control element the output of which is connected to control input of the second shaper of each channel.

EFFECT: scheme is simplified and reliability of single-phase bridge SVI is improved.
