Recent and Future IGBT Evolution

IGBT module has many variations in order to find out an optimum saddle point on a triangle trade-off relationship among low loss, fast switching and robustness. One of the best solution, especially for automotive application, which requires the perfect safety, is the IPM with a protection circuit built-in inside of power module. In IPM, low loss characteristics could be achieved by the advanced IGBT structure like a CSTBT. Not only individual technology advance for both Silicon chip and package, but also chip-package interconnections are extremely important to achieve the best performance as a power module.
