METHOD TO CONTROL DEPENDENT INVERTER OF SINGLE-PHASE AC CURRENT Russian patent published in 2015 - IPC H02M7/162 H02M1/08 G05F1/565 B60L7/10 B60L7/16 

FIELD: electricity.

SUBSTANCE: in a method to control dependent inverter of single-phase AC current at specified in the application materials control of valves of anode and cathode groups of the dependent inverter bridge in the first and second half-periods of control pulses with an adjustable angle β_adj and a non-adjustable angle β in the respective areas for adjustment auxiliary control pulses are supplied in all areas for adjustment, except for the first one, in the first half-period of voltage at the non-adjustable angle β to a controlled valve of the cathode group in the middle circuit of the previous area and in the second half-period - a controlled valve of the anode group in the middle circuit of the previous area. The control pulses at the non-adjustable angle β supplied in each half-period to one respective pair of the controlled valves at the outermost circuits of the respective areas are supplied with time delay regarding the non-adjustable angle β to the value of the opening angle γ1 for the respective controlled valve in the middle circuit of the previous area.

EFFECT: higher power factor for the inverter.
