CONTROL DEVICE AND CONTROL METHOD Russian patent published in 2019 - IPC H02P6/08 

Abstract RU 2682664 C1

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Control device for controlling an electrical unit, comprising: pair of switching elements capable of converting power from the power source to AC power and supplying AC power to an electrical unit, conversion unit, calculation unit, generation unit, control unit, determination unit, correction unit. Technical result is achieved by the fact that on the basis of determining whether the amplitude of the carrier signal increases or decreases, produced by the determination unit, the correction unit adjusts the switching time of the switching element by adjusting the filling instruction value calculated by the calculation unit.

EFFECT: providing a control device and a control method to counteract the reduction in the detection accuracy of the alternating current applied to the electrical load.
