STEP-UP/STEP-DOWN VOLTAGE CONTROLLER Russian patent published in 2016 - IPC H02M5/22 

FIELD: electronics.

SUBSTANCE: invention relates to power electronics and can be used for generation of controlled and stable three-phase alternating voltage, wherein quality of input and output current remains high. Disclosed AC voltage regulator comprises in each phase accumulation reactors connected in series with power supply, capacitors connected in parallel to load, two three-phase diode rectifier bridges, first of which is connected by AC outputs to terminals of load, and by second AC outputs to load through capacitors, as well as two transistors, each one connected in conducting direction to DC outputs of diode rectifier bridges.

EFFECT: technical result is designing a simple AC voltage regulator with a wide range of control.
