Document Type and Number:
WIPO Patent Application WO/2021/179302
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a wireless power supply device, a wireless powered device, a wireless power transmission system and a manufacturing method thereof. The wireless power supply device comprises a first circuit coupled to a DC supply and configured to convert a DC voltage of the DC supply into an AC voltage to enable wireless power transmission between the wireless power supply device and a powered device; 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; and 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. In this way, a low cost and high quality dynamic response and output regulation may be achieved.
