Abstract
A power source unit for use in vehicle is disclosed that effectively transfers energy between two power sources. The power source unit includes a main power source connected to input terminals of a current control circuit, such as insulation type power transfer circuit. In addition, a terminal of the main power source is connected to an output terminal of the current control circuit. The other terminal of the main power source is connected to a terminal of a parallel connection of a secondary power source and an electric power unit. The other terminal of the parallel connection is connected with a second output terminal of the current control circuit. Hence, energy from the main power source is transferred to the parallel connection of the secondary power source and electric power unit under the control of the current control circuit.
