DRIVE CIRCUIT AND METHOD FOR A GATED SEMICONDUCTOR SWITCHING DEVICE |
摘要 |
Drive circuit and method for a gated semiconductor switching device A drive circuit and method for a gated semiconductor switching device (10) comprising providing coupling such as a mutual inductance between a gate drive circuit (21) for the device and a drain to source current supply circuit (22) for the device in order to change a gate voltage provided by the gate drive circuit dependent on a rate of change of a current in the drain to source current supply circuit. The change in gate voltage has a magnitude and phase arranged to increase or decrease a switching speed of the gated semiconductor switching device. |

1. A drive circuit forming a combination with a gated semiconductor switching device having a gate drive circuit and a drain to source current supply circuit, the drive circuit comprising: coupling circuitry to form a mutual inductance coupling between a the gate drive circuit and the drain to source current supply circuit to change a gate voltage provided by the gate drive circuit dependent on a rate of change of a current in the drain to source current supply circuit, the change in gate voltage having a magnitude and phase arranged to change a switching speed of the gated semiconductor switching device. |
