| 发明名称 | Soft-switching gate control | ||
| 摘要 | Soft-switching gate control circuitry is disclosed. The circuitry includes a first discharge circuit coupled across a first switching device. A first control circuit, upon a first switch input signal transitioning from a disabled state to an enabled state, is adapted to cause the first discharge circuit to transition from a high impedance state to a discharge impedance state, and when a voltage across the first switching device drops below a first threshold value, cause the first switching device to transition from an off state to an on state. | ||

| 主权项 | 1. Soft-switching gate control circuitry comprising: a first discharge circuit coupled across a first switching device; and a first control circuit, upon a first switch input signal transitioning from a disabled state to an enabled state, adapted to: cause the first discharge circuit to transition from a high impedance state to a discharge impedance state to reduce a voltage across the first switching device; andwhen the voltage across the first switching device drops below a first threshold value, cause the first switching device to transition from an off state to an on state. | ||
