EV/HEV On-Board Chargers and DC-DC Converters

On-board chargers are used to recharge the battery in electric or plug-in hybrid vehicles. They must have high efficiency and power density to keep the weight low. Long-term trends require bidirectional architectures to allow the transfer of power from the battery to the grid, and high frequency switching to reduce the overall size and weight of the charger.

DC-DC converters are used to transfer energy from one battery to another. High efficiency and high power density are extremely important to keep the overall weight and size to a minimum.
