POWER CONVERTER DEVICE AND METHOD OF DEVICE CONTROL Russian patent published in 2014 - IPC H02P27/06 H02M7/48 

FIELD: electricity.

SUBSTANCE: power converter device is made so that its arm comprises two groups of semiconductor devices connected in series. Each group of semiconductor devices comprises a switching element and semiconductor element, different from the switching element, connected in parallel. The connection point, to which groups of semiconductor devices are connected in series, is an outlet AC lead. Both ends of the arm are DC leads. Besides, the power converter device comprises also a current sensor, a module of voltage control command generation, a module to calculate voltage drop and a module of switch control.

EFFECT: increased accuracy of output voltage generation due to compensation of voltage drop in semiconductor elements.
