Overvoltage protection system for wireless power transfer systems |
摘要 |
A wireless power transfer overvoltage protection system is provided. The system includes a resonant receiving circuit. The resonant receiving circuit includes an inductor, a resonant capacitor and a first switching device. The first switching device is connected the ends of the inductor. The first switching device has a first state in which the ends of the inductor are electrically coupled to each other through the first switching device, and a second state in which the inductor and resonant capacitor are capable of resonating. The system further includes a control module configured to control the first switching device to switching between the first state and the second state when the resonant receiving circuit is charging a load and a preset condition is satisfied and otherwise, the first switching device is maintained in the first state. |

1. A wireless power transfer overvoltage protection system comprising:
a resonant receiving circuit comprising, an inductor, a resonant capacitor and a first switching device, the inductor having a first end and a second end, the first switching device being connected between the first end and the second end of the inductor, the resonant receiving circuit being connected to a rectifier and a filter capacitor, the first switching device having a first state in which the first end and the second end of the inductor are electrically coupled to each other through the first switching device, and a second state in which the inductor and resonant capacitor are capable of resonating; and a control module configured to control the first switching device to switching between the first state and the second state when the resonant receiving circuit is charging a load and a preset condition is satisfied and otherwise, the first switching device is maintained in the first state. |
