VOLTAGE INVERTER Russian patent published in 2006 - IPC H02M7/5375 

FIELD: electric engineering, possible use for autonomous provision of electricity to consumers by conversion of voltage of direct current source to alternating voltage.

SUBSTANCE: circuit contains clock impulse generator, inverter launch block, power filter, commutating transistors, increasing transformer. Power input of clock impulse generator elements is connected to output of power filter by input connected to direct current source, while its positive pole is connected to middle point of primary winding of increasing transformer in parallel to secondary winding, where smoothing capacitor is connected. Outputs of primary winding of increasing transformer are connected to appropriate outputs of first and second commutating transistors connected to one another by inputs. As first and second commutating transistors field transistors are used, drains of which are connected to negative pole of direct current source through additional resistor and bridging contact of intermediate relay, connected to each other. Launch block is installed, providing achievement of technical effect.

EFFECT: expanded functional capabilities of voltage inverter, increased reliability of inverter during launch and/or in case of power failures; usage of field transistors, commutating ones in particular, increases overload capacity of voltage inverter, its efficiency, decreases drifting of output voltage, improves mass-dimensional characteristics.
