POWER SUPPLY APPARATUS CAPABLE OF IMPEDANCE MATCHING

WIPO Patent Application WO/2022/028265

A1

A power supply apparatus (100) capable of impedance matching, comprising a power supply module (110) and at least one impedance matching circuit (120). The power supply module (110) is used for supplying power to an external device. The impedance matching circuit (120) is arranged before or after the power supply module (110), and comprises a plurality of impedance elements (121), at least one input end (126), and at least one output end (127). The plurality of impedance elements (121) constitute a mesh structure (123) comprising at least one grid (122), and the grid (122) has edges (124) and vertices (125). Each input end (126) is connected to one vertex (125) in the at least one grid (122). Each output end (127) is connected to another vertex (125) in the at least one grid (122). The power supply apparatus (100) can perform impedance matching on the power supply module (110) and the external device by means of the impedance matching circuit (120) therein, thereby ensuring that a signal generated by the external device is transmitted without distortion while the power is supplied to the external device.
