| 发明名称 | Charge recovery in power converter driver stages | ||
| 摘要 | A power converter includes a first transistor operable to source current to a load when switched on, a second transistor operable to freewheel inductor current or sink current from the load when switched on, and a driver circuit. The driver circuit is operable to switch the first transistor on and the second transistor off during a first period, switch the first transistor off and the second transistor on during a third period after the first period, and connect a gate of the first transistor to a gate of the second transistor during a second period between the first and third periods when the gates of both transistors are floating. | ||
