<p>PROBLEM TO BE SOLVED: To provide a bidirectional DC/DC converter device whose efficiency is improved by improving cooling means.SOLUTION: A housing 100 is separated into a first area 10 and a second area 20 by a partition plate 30. In the first area 10, a bridge circuit BCconnected to a DC power supply E, a cooling unit CU, a current detection circuit 11, a fan rotation frequency adjustment circuit 12, and a cooling fan CFare installed, and in the second area 20, a bridge circuit BCconnected to a DC power supply E, a cooling unit CU, a current detection circuit 21, a fan rotation frequency adjustment circuit 22, and a cooling fan CFare installed. Temperature Tais adjusted by operating the cooling fan CFat a rotation frequency set by the fan rotation frequency adjustment circuit 22 so that a diode element of the bridge circuit BCoperates in a high-temperature state, in the case of supplying power from the DC power supply Eto the DC power supply E. Temperature Tais adjusted, using the similar principle, by operating the cooling fan CFso that a diode element of the bridge circuit BCoperates in a high-temperature state, in the case of the reverse power flow.</p> |
