| Zusammenfassung: | When first and second intelligent power module type semiconductor switching circuits configured by an IGBT respectively are connected in parallel, collectors of IGBT are connected to each other, and emitters of the IGBT are connected to each other. And, a resistor is connected to each of the emitters. Both of the resistors and have the same resistance value. Then, the emitters are connected to each other by an emitter auxiliary terminal connection line via this resistor and the auxiliary terminal. In addition, gates of the IGBT and the IGBT are connected to each other by a gate auxiliary terminal connection line via this resistor and a ferrite beads core that has a high impedance at a predetermined frequency. |
