Electronic architecture for controlling a dc/ac voltage converter

Abstract

Electronic architecture (3) for controlling a DC/AC voltage converter (2), said converter (2) comprising a plurality of arms mounted in parallel, each arm comprising two controllable switching cells (21), in series and separated by a mid-point, the arms being paired in H-bridges (20), the architecture (3) comprising: —a main control unit (36), configured to communicate through a potential barrier (61) with a remote control unit (35), and —a plurality of secondary control units (37), each secondary control unit (37) being dedicated to controlling a respective H-bridge (20), and comprising: —a processing unit (40) for processing the information received from the main control unit (36), and —a monitoring unit (41) for monitoring the controllable switching cells (21) of said H-bridge (20), said monitoring unit (41) being configured to modify the state of all or some of said switching cells (21) of said H-bridge (20) at least on the basis of information received from the corresponding processing unit (40).
