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 9):
The switching circuit according to  claim 1 , further comprising\n a double-sided wiring board which includes a conductor for wiring on a front surface and a back surface, wherein the main switching device and the drive circuit are disposed on the front surface, a through hole is provided, which is connected from a vicinity of each of the second source terminal, the negative electrode terminal, and a source terminal of the second switch element to a conductor for source wiring disposed on the back surface, and the conductor for source wiring is disposed to include an area on the back surface of the double-sided wiring board, the area corresponding to an area of projection when the gate terminal, the second source terminal, and the drive circuit on the front surface of the double-sided wiring board are projected onto the back surface.
