Abstract |
The interest is coming to be high, recently with depletion of the fossil fuel and with carbon dioxide exhaust limit about emittion, from a car of Internal combustion engine to Electric vehicle. AC-DC converter is necessary to battery charging which is an electric vehicle energy storage. Necessary conditions of the converter are necessary for wide output voltage range, high efficiency, high power factor etc.It is composed two stages for wide output voltage range and insulation. Preliminary stage uses LLC resonant converter and the after stage uses BOOST converter PFC circuit for being considered a power factor and confirmed experimentally. |
