CIRCUIT AND TOPOLOGY FOR HIGH RELIABILITY POWER ELECTRONICS SYSTEM Russian patent published in 2014 - IPC G05B9/03 H03K17/00 

FIELD: physics; control.

SUBSTANCE: invention relates to power electronics. Disclosed is a power electronics system comprising a set of identical semiconductor switching devices connected in series to provide high reliability switching, wherein each semiconductor switching device is configured to be activated through a corresponding switch driver unit, comprising a built-in logic unit, and a set of identical controller units, wherein each logic unit is configured to provide the corresponding control signal of the semiconductor switching device upon receiving output signals from the controller units, wherein each output signal corresponds to one switch driver unit and the corresponding logic unit and is connected to the corresponding built-in logic unit and the switch driver unit, such that the corresponding semiconductor switching device is controlled as a result of logic processing of signals of said set of controller units independent of faults in any one or more controller units, provided that at least a minimum number of controller units remains operational.

EFFECT: simple backup circuit of a power electronics system while maintaining reliability thereof.
