ALTERNATING VOLTAGE REGULATOR Russian patent published in 2015 - IPC H02M5/275 

FIELD: electricity.

SUBSTANCE: regulator can be applied as three-phase alternate voltage stabiliser, transformer-free device of alternate voltage stepping-up, adjustable source of stable alternate voltage, or as smooth start device for asynchronous motors. Regulator includes reactor included in power source at input, with one condenser inserted in each phase and connected in parallel to power source with its own reactor, and additionally includes two three-phase diode bridges and two transistors, where input of first three-phase diode bridge is connected to one end of circuit comprised by power source, condenser and reactor, output of first diode bridge is connected to first transistor, the other end of circuit is connected to second three-phase diode bridge, out put of second three-phase diode bridge is connected to second transistor, and input of second three-phase diode bridge is connected to a load comprised by a reactor and resistance sequence.

EFFECT: voltage regulation and increase without the use of power supply network transformer.
