POWER CONVERSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power conversion device whose reliability can be improved while reducing the size thereof.SOLUTION: A power conversion device 10 comprises a semiconductor module 50 and a control board 30. The semiconductor module 50 is provided in a high voltage region in the power conversion device 10. The control board 30 includes a low voltage region electrically insulated from the high voltage region. The power conversion device 10 also comprises an insulation transmission member 60. The insulation transmission member 60 transmits a signal and power between a first transmission unit 61 and second transmission unit 62 while performing electrical insulation between the first transmission unit 61 and second transmission unit 62. The first transmission unit 61 is attached to a control terminal 50a of the semiconductor module 50 in the high voltage region. The second transmission unit 62 is attached to the low voltage region of the control board 30 and is arranged so as to face the first transmission unit 61.SELECTED DRAWING: Figure 1
