Title:
POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2019047571
Kind Code:
A
Abstract:
To provide a power conversion device capable of supplying power from an input unit to an output unit, even when a state in which use of a power supply path from the input unit to the output unit via a transformer should be refrained as much as possible has occurred.SOLUTION: The power conversion device supplies power from an input unit to which a DC power source 100 is connected, to an output unit via a transformer Tr11 and a power conversion circuit 10. The power conversion device includes a choke coil L13, an auxiliary coil L14, and a control unit 300. The auxiliary coil L14 is connected to the output unit, is magnetically coupled with the choke coil L13, and is wound so as to allow current to flow therethrough from the negative electrode side to the positive electrode side of the output unit when the current flows from the DC power source 100 to the choke coil L13. The control unit 300 controls a switch to supply power from the DC power source 100 to the output unit via the choke coil L13 and the auxiliary coil L14, so as not to generate a magnetic flux in a first coil L11, and so as not to cause the current to flow in a second coil L12.SELECTED DRAWING: Figure 1
