Novel Operating Mode for DC-to-DC Converters in PHEVs

The demand on the DC-to-DC converters is increasing and more capable units are required. In this paper we will introduce a third mode of operation that will allow the Plug-In Hybrid Vehicle (PHEV) to meet the LV load demand without weight or cost increase. This mode operation will utilize the DC-to-DC converters of the on-board charger to compensate for the increase in load demand.
