Abstract
A Miller clamping circuit for driving a wide bandgap (WBG) device is provided. The Miller clamping circuit comprises: a semiconductor switching device having high side terminal connected to gate of the WBG device; and low side terminal connected to source of the WBG device; a first diode having anode connected to ground terminal of a driver IC chip; and cathode connected to control terminal of the switching device; a first resistor connected in parallel with the first diode; a second resistor having a first end connected to the ground of the driver IC chip; a second diode having anode connected to the low side terminal of the switching device and cathode connected to a second end of the second resistor; and a third resistor connected in parallel with the second diode. The Miller clamping circuit is configured to suppress a false turn-on and gate-loop oscillation of the WBG device simultaneously.
