Latest Patents

Saori Uchida holds a patent for a power switching device that effectively decreases both surge voltage and switching loss. The invention involves an inductor connected to the emitter electrode of an IGBT (Insulated Gate Bipolar Transistor) element. This design allows the potential of the emitter electrode to change in a manner that maintains the IGBT element in the ON state while the main current attenuates during the transition from ON to OFF. The inclusion of the inductor in the OFF driving current path ensures a smooth transition, thereby suppressing surge voltage. Additionally, since the inductor is excluded from the ON driving current path, the transition from OFF to ON occurs rapidly, resulting in a significant reduction in switching loss. This dual benefit of decreased surge voltage and switching loss is a remarkable achievement in power electronics.
