Development of a hybrid EV on board charger. This charger is the size of a shoe box; it can be either fed by DC or by conventional AC. On DC it can take up to 700VDC and will be able to charge up to 21kW. Withthe future EV this will correspond to 400km/hr charging. On conventional three phase 400VAC, it will charge with 7kW, corresponding to 130km/hr
