Abstract: A system charges a traction battery of an at least partially electric traction vehicle. The system includes an input filter connected to a power supply network. The filter includes a capacitance connected through a switch of the filter between at least one power supply phase connection or a neutral connection of the charging system, and a ground of the charging system. The system includes a controller for charging parasitic capacitances of the charging system without transferring energy from the power supply network to the battery while the power supply network is connected to the charging system. The system includes a time delay for closing the switch of the filter when a delay time frame higher than or equal to a predetermined time frame expires. The system also includes a charging activator for transferring energy between the power supply network and the battery, the switch of the filter being closed.

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.
