An electrical architecture () for converting DC voltage into AC voltage, and vice versa, comprising:&#x2014;a DC/AC voltage converter (), comprising a plurality of arms mounted in parallel, each arm comprising two controllable switching cells (), in series and separated by a mid-point, the arms being paired in H-bridges (),&#x2014;for each H-bridge (), a dedicated control member (), such that all of the switching cells () of said H-bridge () can be controlled by this control member (), each control member () being intended to communicate with a same remote control unit () through a potential barrier ().

Electrical architecture for converting DC voltage into AC voltage, and vice versa

The invention relates to a voltage converter comprising: an isolated DC/DC converter circuit having at least one first isolation transformer and switches whose opening and closing successions with at least one duty ratio make it possible to transmit energy through the isolated DC/DC converter by way of said first transformer; a circuit for regulating the input voltage of the isolated DC/DC converter circuit; the regulating circuit being configured to control the output voltage of the isolated DC/DC converter circuit by modifying the voltage delivered to the isolated DC/DC converter circuit, the duty ratio of the isolated DC/DC converter circuit remaining constant, and in said converter, the output of the regulating circuit is connected to a branch of the isolated DC/DC converter circuit comprising said first transformer.
