<p>A voltage conversion apparatus (1) is connected between a first charging/discharging device (3) and a second charging/discharging device (4), and performs voltage conversion between the first and second charging/discharging devices. The apparatus includes a first switching device (11) having one terminal connected to the first charging/discharging device, a second switching device (12) connected between the other terminal of the first switching device and the earth, a third switching device (13) having one terminal connected to the second charging/discharging device, a fourth switching device (14) connected between the other terminal of the third switching device and the earth, and a coil provided between the other terminal of the first switching device and the other terminal of the third switching device. A controller (31) is provided for controlling the first through fourth switching devices, such that the first and fourth switching devices are switched on and off in the same phase, and the second and third switching devices are switched on and off in the same phase that is reverse to that of switching of the first and fourth switching devices. <IMAGE></p> |
