Abstract: A charging system for electric vehicles is disclosed, which includes at least one charging port with an interface for power exchange with at least one electric vehicle, and at least one power converter for converting power from a power source such as a power grid to a suitable format for charging the vehicle. The power converter can be at a remote location from the charging port, such as a separate room, and/or a separate building.

Abstract: A resonant power converter includes a resonance tank formed by a capacitance component and an inductance component, at least two switches connected to the resonance tank and a voltages source in a bridge configuration, a number of snubber capacitors connected in parallel to each of the switches, a controller configured to control ON and OFF timings of the at least two switches so as to excite the resonance tank, and a voltage sensor configured to sense a voltage drop across at least one of the switches. The controller is configured to switch the at least one of the switches to the ON state when the absolute value of the sensed voltage drop reaches a minimum.
