Abstract :
This paper addresses the need for negative gate bias with IGBT devices that experience a dv/dt when in the off-state. Factors considered include gate bias voltage, gate impedance, reapplied dv/dt and case temperature. Experimental results for a high-voltage high-current IGBT support the assessment of these factors
