Abstract: A battery charging device for a motor vehicle battery with at least partially electric traction includes a filtering stage to be connected to an electrical power supply network, a voltage buck stage connected to the filtering stage, a voltage boost stage coupled to the voltage buck stage and to be connected to the battery, and a regulation unit to impose chopping duty cycles on the voltage buck stage and on the voltage boost stage. The regulation unit compensates the harmonics generated by the voltage buck stage in the filtering stage, acting on the voltage buck stage.

Abstract: A system for controlling a power converter, the system configured to control at least two consecutive instances of closure of pairs of controlled switches including a bottom switch and a top switch. A measurement mechanism can measure, prior to a transition between closing of one pair of controlled switches and closing of another pair of controlled switches, electric potential at a connection point for at least two arms in which the controlled switches are affected by the transition. A comparison mechanism compares the measured potentials and a selection mechanism can select the top switch of the arm with a lowest measured electric potential and the bottom switch of the arm with a highest measured electric potential. A controller can control closing of the controlled switches selected during at least one additional time period around the transition.
