Title:
POWER CONVERSION DEVICE, CHARGE/DISCHARGE DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/048685
Kind Code:
A1
Abstract:
This power conversion device converts power in order to transfer power in both directions between a first apparatus and a second apparatus and comprises: a transformer unit having a core, a plurality of primary-side windings wound around the core, and a secondary-side winding wound around the core; a first circuit for transferring power between each of the plurality of primary-side windings and the first apparatus; and a second circuit for transferring power between the secondary-side winding and the second apparatus. The plurality of primary-side windings are each connected to the first circuit via a separate filter so that the frequency bands of power whereby each of the primary-side windings are made to operate differ from each other between the plurality of primary-side windings, and the first circuit and the second circuit are configured so that the frequency of power whereby the transformer unit is made to operate can be changed in accordance with the primary-side winding used for power conversion in the transformer unit among the plurality of primary-side windings.
