Gate drive circuit with a voltage stabilizer and a method

摘要

The present invention concerns The gate drive circuit comprising means (V2, V3) for creating bipolar voltage to a gate (X4) of a IGB transistor and means (V1, C3) for compensating for Miller currents of the IGB transistor. In accordance with the invention the means (V1, C3) for compensating are formed by a switching element (V1) connected in series with a capacitor (C3) between the gate (X4) and supply voltage (10).
