HF oscillation prevention circuit for power semiconductor module uses inductors and capacitors for de-tuning oscillator provided by parallel semiconductors

摘要

The circuit provides de-tuning of the oscillator provided by parallel semiconductor elements, e.g. power transistors or diodes, using parallel connection of a series inductor (Lb) and capacitor (Cb) across each semiconductor, or a pair of inductors and a capacitor connected in a T-configuration between the semiconductors.
