Title:
POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2020068600
Kind Code:
A
Abstract:
To provide a power conversion device that suppresses a surge voltage to a switching element.SOLUTION: A power conversion device 10 is connected between DC buses 3a and 3b and consumes a regenerative power flowing through the DC buses 3a and 3b. The power conversion device 10 includes a switching element 12, a resistor 14 connected in series with the switching element 12 between the DC buses 3a and 3b, and a diode 13 that is connected in parallel to the resistor 14 and returns a reverse voltage due to the parasitic inductance of the resistor 14. The length of a first wiring between the switching element 12 and the diode 13 is shorter than the length of a second wiring between the resistor 14 and the diode 13.SELECTED DRAWING: Figure 1
