Title:
電力変換装置
Document Type and Number:
Japanese Patent JP6669532
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion device capable of reducing a loss.SOLUTION: A first inverter 20 of a power conversion device 15 has first switching elements 21-26, and is connected with one ends 111, 121, and 131 of coils 11, 12, and 13 and with a first battery 41. A second inverter 30 has second switching elements 31-36, and is connected with the other ends 112, 122, and 132 of the coils 11, 12, and 13 and with a second battery 42. A controller 65, in a case where a drive request of a motor generator 10 is in a difference voltage region RD, controls the first inverter 20 and the second inverter 30 by difference voltage control that application voltages of the coils 11-13 become a voltage depending on a difference between a first power supply voltage V1 and a second power supply voltage V2. By performing the difference voltage control, the voltages applied to the coils 11-13 can be lowered, and thereby, a loss can be reduced.SELECTED DRAWING: Figure 1
