Abstract
The electric conversion stage according to the invention can be connected on one hand to intermediate terminals of a DC voltage electric bus, and on the other hand to output terminals. It comprises P switching branches, P≧2, the switching branches being connected in parallel between the intermediate terminals, each switching branch including first and second controllable electronic switches connected serially and connected to each other by a midpoint, each switch including a semiconductor switching element and a diode connected in anti-parallel to the semiconductor element, and means for controlling the electronic switches according to a control law. It also comprises a capacitor connected between the two output terminals and, for each switching branch, an electromagnetic coil connected between a terminal of the capacitor and the midpoint of the corresponding switching branch, and the control law is selected from among a first control law and a second control law, the first control law being such that the semiconductor element of each first switch is always off, and the second control law being such that the semiconductor element of each second switch is always off.
