  "textContent": "Wireless power supply devices, wireless powered devices, wireless power transmission systems, and manufacturing methods thereof. The wireless power supply device can include a first circuit configured to convert a DC voltage to an AC voltage for wireless power transmission between the wireless power supply device and a powered device. The system can also include a pulse signal receiver configured to receive a first pulse signal from the powered device and to generate a second pulse signal based on the first pulse signal, the first pulse signal being generated based on a feedback signal of the powered device indicating information associated with received power of the powered device. The system can also include a first control unit coupled to the first circuit and the pulse signal receiver, and configured to control conversion of the first circuit based on the second pulse signal.",
