Abstract

A boosting-charge power supply apparatus and a boosting-charge power supply method are capable of supplying electric power for boosting charge to a variety of mobile bodies using a single apparatus and supplying high-quality electric power to the mobile bodies.

A boosting-charge power supply apparatus 10 which supplies electric power for boosting charge to a mobile body having a boosting-charge control function includes: a rectifier 11 for supplying DC power; a first power storing means 15 for storing DC power from the rectifier 11 and outputting pure DC power; a charging circuit 20 which sends pure DC power from the first power storing means 15 directly to a vehicle 50 including a second power storing means 85 for storing DC power from the first power storing means 15; and a power-supply controlling means 12 for stopping the rectifier 11 from supplying electric power to the first power storing means 15 while the first power storing means 15 is supplying electric power to charge the second power storing means 85. Control is executed in such a way that pure DC power supplied from the first power storing means 15 becomes electric power suitable for charging conditions of the second power storing means 85 on the vehicle 50 side, thereby enabling the same boosting-charge power supply apparatus 10 to supply electric power and give a boosting charge to a different type of vehicle. Further, the vehicle 50 can be supplied with high-quality electric power equivalent to pure DC power, thereby almost saving considering a noise, a surge or the like in designing electric circuits of the vehicle 50, so that the electric circuits of the vehicle 50 can be more easily designed.
