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 6):
The switching circuit according to  claim 1 ,\n wherein when a voltage is applied between the gate electrode and the source electrode, the main switching device allows a gate current to flow, and has a diode characteristic such that a voltage between the gate electrode and the source electrode is clamped to a voltage having a gate-clamp voltage value, and the drive circuit has a third resistor connected between the first switch element and the gate terminal.
