When using IGBT for power system design, smooth gate waveform is expected by engineers. Spikes, oscillations on the switching edges are the troubles. It makes the system unstable, unreliable and low efficiency. This paper discusses what kind reasons cause the spike and oscillation during IGBT switching, and, how to optimizing the gate driver to resolve it.
