Abstract
A selectable increase in the common source inductance is obtained by a layout for a power module used for a half-bridge phase leg in an inverter for an electrically-driven vehicle. The power module comprises a pair of transistor dies connected to positive, negative, and AC conductive tracks for carrying bridge currents. The module includes a pair of gate drive pins and a pair of gate drive coils connecting a respective pin and die. The gate drive coils are disposed in a region between the positive and negative tracks containing a flux generated by the currents having a locally greatest rate of change. The coils may preferably be comprised of traces on an auxiliary printed circuit board incorporated in the module. The gate drive pins can be on the gate side or the emitter side of the transistor dies.
