Title:
POWER MODULE
Document Type and Number:
WIPO Patent Application WO/2018/186353
Kind Code:
A1
Abstract:
This power module (2) includes at least one half bridge (1), and comprises, respectively in the upper and lower arms thereof: first transistors Q1, Q4; second transistors QM1, QM4, the drain of each of which being connected to the gate G1, G4 side of the respective first transistors, the source of each of which being connected to the source S1, S4 side; source signal wiring patterns SSP1, SSP4 connected to the source of the respective first transistors; first connection conductors MSW1, MSW4 connecting the respective source signal wiring patterns and the source of the respective second transistors; second gate signal wiring patterns MGP1, MGP4 connected to the gate MG1, MG4 of the respective second transistors; and second connection conductors MGW1, MGW4 connecting the respective second gate signal wiring patterns and the gate of the respective second transistors. The length of each first connection conductor is shorter than or equal to the length of each second connection conductor. Thus, a power module having a high-speed switching performance and in which malfunctions are suppressed is provided.
