Abstract:
A switching circuit includes main switching a device and a drive circuit. The main switching device has a gate terminal, a drain terminal, and a first source terminal through which a main current flows, and a second source terminal for gate drive connected to drive circuit. The drive circuit has a bias capacitor having a negative electrode terminal connected to the second source terminal, a first series circuit formed between a positive electrode terminal and the gate terminal by connecting a high-side switch, a resistor, and a capacitor in series, and a second series circuit formed between the gate terminal and the second source terminal by connecting the capacitor, a resistor and a low-side switch in series. The drive circuit adjusts each of gate charge and discharge currents, and further damps the oscillation of the waveform of gate current/voltage.

Claim (Index 3):
The switching circuit according to  claim 1 ,\n wherein the main switching device has two parasitic capacitances one of which between the gate electrode and the source electrode and the other between the gate electrode and the drain electrode, and a resistance value of the second resistor is a value greater than a square root of a quotient of an inductance value of the second parasitic inductance divided by a value of capacitance of a circuit in which the capacitor and an equivalent capacitor having a capacitance of a sum of the parasitic capacitances are connected in series.
