Patent number: 11937370Abstract: A base material is provided. A first patterned circuit layer and a second patterned circuit layer are formed on a first surface and a second surface of the base material. A first insulation layer and a metal reflection layer are provided on the first patterned circuit layer and a portion of the first surface exposed by the first patterned circuit layer, wherein the metal reflection layer covers the first insulation layer, and a reflectance of the metal reflection layer is substantially greater than or equal to 85%, there is no conductive material between the first patterned circuit layer and the metal reflection layer. A first ink layer is formed on the first insulation layer before the metal reflection layer is formed.Type: GrantFiled: September 1, 2021Date of Patent: March 19, 2024Assignee: UNIFLEX Technology Inc.Inventors: Cheng-I Tu, Ying-Hsing Chen, Meng-Huan Chia, Hsin-Ching Su, Yi-Chun Liu, Cheng-Chung Lai, Yuan-Chih Lee

Patent number: 11532982Abstract: The disclosure provides a power supply and an operation method thereof. The power supply includes a power factor correction (PFC) circuit, a resonant conversion circuit and a dead zone control circuit. The PFC circuit performs power factor correction to output a corrected voltage. The resonant conversion circuit is coupled to the PFC circuit to receive the corrected voltage. The resonant conversion circuit converts the corrected voltage into a converted voltage. The dead zone control circuit is coupled to the resonant conversion circuit to receive the switch voltage. The dead zone control circuit controls the PFC circuit to adjust the corrected voltage. The dead zone control circuit observes the change trend of the falling time of the switch voltage in the deadtime by adjusting the corrected voltage. The dead zone control circuit determines the corrected voltage according to the change trend of the switch voltage.Type: GrantFiled: May 6, 2021Date of Patent: December 20, 2022Assignee: Chicony Power Technology Co., Ltd.Inventors: Tso-Jen Peng, Mao-Song Pan, Yi Ching Su

Patent number: 10312725Abstract: A power supply system with identification code updating capability is used for providing an electric power to an electronic device having a first identification (ID) code. The power supply system includes a power supply device and an ID code updating module. The power supply device is configured to provide the electric power to the electronic device and includes a memory unit. The memory unit is configured to store a look-up table including at least one second ID code. The ID code updating module is electrically connected to the power supply device. When the second ID code listed in the look-up table does not match with the first ID code of the electronic device, the ID code updating module updates a second ID code matching with the first ID code in the look-up table. A charging method is further disclosed.Type: GrantFiled: February 3, 2016Date of Patent: June 4, 2019Assignee: CHICONY POWER TECHNOLOGY CO., LTD.Inventors: Yi-Ching Su, Yang Wang
