Title:
POWER CONVERSION DEVICE, CHARGING DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/089865
Kind Code:
A1
Abstract:
This power conversion device comprises: a transformer that includes first and second coils; a first bridge circuit that includes a plurality of first switching elements and that is connected to the first coil; and a second bridge circuit that includes a plurality of second switching elements and that is connected to the second coil. The first bridge circuit generates a first AC voltage and supplies the same to the first coil. The second bridge circuit converts a second AC voltage generated on the second coil and outputs the resulting voltage. The power conversion device switches, in accordance with transmission power, between phase difference control for adjusting a phase difference between the second AC voltage and the first AC voltage and burst control for adjusting a period of supplying the first AC voltage while keeping a phase difference constant and fixing one cycle of the control.
