Abstract
A control circuit includes a detection module configured to detect an operating condition of a semiconductor switching device; a determining module configured to determine a gate allowable voltage of the semiconductor switching device based on the operating condition; and an output module configured to output a control signal to a driving power supply circuit of the semiconductor switching device based on the gate allowable voltage, to control the driving power supply circuit to provide a gate on voltage that is not higher than the gate allowable voltage and that is positively correlated with the gate allowable voltage for the semiconductor switching device. When the operating condition of the semiconductor switching device becomes better, the gate allowable voltage of the semiconductor switching device is increased.
