Document Type and Number:
Japanese Patent JP7208188
Kind Code:
B2
Abstract:
To suppress power loss in a power conversion device.SOLUTION: A power conversion device is configured to comprise: a transformer 22 that has a primary coil 24, a first secondary coil 26 and a second secondary coil 28; a first secondary switching circuit 30 connected with the first secondary coil 26; a second secondary switching circuit 36 connected with the second secondary coil 28; and an intermediate capacitor 38 included in the second secondary switching circuit 36. In this power conversion device, a power is supplied from the first secondary switching circuit 30 to the intermediate capacitor 38 via the transformer 22 by switching operations of the first secondary switching circuit 30 and the second secondary switching circuit 36. Further, a power is outputted from the intermediate capacitor 38 to an auxiliary battery 40 via a midway point of the second secondary coil 28 by a switching operation of the second secondary switching circuit 36.SELECTED DRAWING: Figure 1
