FREQUENCY CONVERTER AND METHOD FOR CONTROL THEREOF Russian patent published in 2015 - IPC H02M1/88 H02M5/443 H02M5/451 H02M7/66 H02M7/77 H02M7/797 H05B6/02 H05B6/10

Abstract RU 2562254 C1

FIELD: electricity.

SUBSTANCE: fourth bridge circuit is introduced into a frequency converter. The load is comprised of two parallel sections connected in series between inverting bridge circuits of two parallel circuits. The invention discloses a control method for the frequency converter.

EFFECT: continuous control of symmetry and voltage value for an inductor output in regard to the earthed neutral of the supply mains, rapid voltage decrease for the load when controlled voltage exceeds the preset value, reliable and smooth cut-out of the converter at the breakdown of the load output to the earthed neutral, increased efficiency factor for the inductor, smoothed shape of output current.
