<p>PURPOSE:To obtain an efficient power source by controlling a power converter to gain the maximum power from an induction coil provided in a vehicle. CONSTITUTION:An indiction coil 1 of a power source for a vehicle is arranged in addition to a propulsion coil on the vehicle in response to the propulsion coil on the ground, and the output terminal of the coil 1 is connected through a power converter 20 to a storage battery 30. A control circuit 60 obtains a reference value to attain the maximum current from the first detection signal S1 relating to the speed, frequency or induced voltage from a transformer 40, and forms a control signal 100 for controlling the converter 20 so that the second detection signal S2 as to the current applied to the converter 20 from the current detection current transformer 50 reaches the above reference value. In this manner, the efficient power source can be obtained.</p> |
