Abstract
An adaptive gate drive circuit for an insulated gate bridge transistor, IGBT, based semiconductor switch provides a gate resistance device for reducing timing delays and switching losses associated with an increase in switch junction temperature. The gate resistance device is disposed close to the switch junction and including a negative temperature coefficient, NTC, thermistor and linear gate resistor connected in parallel. When the thermistor senses an increase in the junction temperature of the semiconductor switch, gate resistance via the linear gate resistor is reduced to bring the junction temperature back to thermal equilibrium with minimal delay, allowing the semiconductor switch to switch faster and reducing associated switching losses.
