In a direct current (DC) power conversion device according to an embodiment, a first bridge circuit is driven by a first drive signal and converts first DC power of a first DC voltage into first alternating current (AC) power. A second bridge circuit is driven by a second drive signal and converts second DC power of a second DC voltage into second AC power. An inductance element is provided between the first bridge circuit and the second bridge circuit. A control device decides a phase difference between the first drive signal and the second drive signal using phase shift control based on a dual active bridge (DAB) scheme, generates each of the first drive signal and the second drive signal for driving the first bridge circuit and the second bridge circuit in accordance with the phase difference, and drives the first bridge circuit and the second bridge circuit using the first drive signal and the second drive signal. The control device determines an allowable range of the phase difference using the first DC voltage and the second DC voltage and generates the first drive signal and the second drive signal between which the phase difference is limited within the allowable range when a magnitude of an electric current flowing through the inductance element is limited.
A direct current (DC) power conversion device based on power conversion control of a dual active bridge (DAB) scheme for transmitting electric power between first DC power and second DC power, the DC power conversion device comprising:
A control method for use in a DC power conversion device based on power conversion control of a DAB scheme for transmitting electric power between first DC power and second DC power, wherein the DC power conversion device includes a first bridge circuit driven by a first drive signal and configured to convert the first DC power of a first DC voltage into first AC power and output the first AC power to a first AC terminal, a second bridge circuit driven by a second drive signal and configured to convert the second DC power of a second DC voltage into second AC power and output the second AC power to a second AC terminal, and an inductance element provided between the first bridge circuit and the second bridge circuit and connected to each of the first AC terminal and the second AC terminal, the control method comprising:
