Title:
POWER SEMICONDUCTOR DEVICE AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/004549
Kind Code:
A1
Abstract:
This power semiconductor device (1) is provided with a pair of semiconductor switching elements (S11, S12) connected in parallel and a drive circuit (2) for driving the semiconductor switching elements (S11, S12), and has: a pair of drive paths (21, 22) for applying drive signals from the drive circuit (2) to each of the pair of semiconductor switching elements (S11, S12); and a pair of main current paths (11, 12) for supplying current to each of the pair of semiconductor switching elements (S11, S12). Magnetic fluxes (Φ1, Φ2) respectively generated in the pair of main current paths (11, 12) penetrate a circuit passing through at least one of the pair of drive paths (21, 22), and the directions of the magnetic fluxes (Φ1, Φ2) are opposed to each other in the peripheries of the drive paths (21, 22).
