Patent number: 11933309Abstract: A method for controlling a fan in a fan start-up stage including a first time period and a second time period comprises the following steps of: during the first time period, continuously providing a first driving signal to drive the fan; and during the second time period, continuously providing a second driving signal to drive the fan; wherein, the signal value of the first driving signal gradually decreases until being equal to the signal value of the second driving signal. Wherein the signal value of the first driving signal non-linearly decreases, the signal value of the second driving signal is an unchanged value. Wherein, the first time period and the second time period are adjusted for a different fan but the sum of the first time period and the second time period is always the same. A fan is also disclosed.Type: GrantFiled: July 22, 2022Date of Patent: March 19, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Yi-Fan Lin, Chung-Hung Tang, Cheng-Chieh Liu, Chun-Lung Chiu

Patent number: 11906555Abstract: Methods and systems for emulating high side current of a power switch including low and high side switches. The method includes generating, with a low side current sensor, a low side current signal for the low side switch when the power switch is in a low state. The method also includes generating, with a first transconductance amplifier, an emulated current signal based on an input voltage of the power switch. The method further includes generating, with a buffer, a fixed reference voltage by sampling the low side current signal when the power switch changes from the low state to a high state. The method also includes generating, with a capacitor, an emulated voltage based on the emulated current signal and the fixed reference voltage. The method further includes, generating, with a second transconductance amplifier, a high side current signal for the high side switch based on the emulated voltage.Type: GrantFiled: April 7, 2022Date of Patent: February 20, 2024Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Mahbub Hasan, Yue Hung Tang

Patent number: 11824388Abstract: A battery of a preselected type advantageously has a beveled edge formed between a front-end surface and a lateral surface of the battery. In a battery charger, a slot has a cap formed with an interior channel for receiving a front-end portion of the preselected-type battery. The cap has a stopping member for stopping the preselected-type battery so as to receive recharging. Advantageously, the stopping member may be shaped to complement the beveled edge for seamlessly receiving the beveled edge when the preselected-type battery is inserted into the slot. A mismatch between the stopping member and a line edge of an unaccepted-type battery causes the stopping member to block the unaccepted-type battery from reaching deeper into the channel than the preselected-type battery when the unaccepted-type battery is inserted, disconnecting a positive charging terminal from the unaccepted-type battery to avoid the charger from accidentally recharging the unaccepted-type battery.Type: GrantFiled: November 15, 2021Date of Patent: November 21, 2023Assignee: GP Technology & Innovation Ltd.Inventors: Chun Bong Leung, Ping Hung Tang, Wei Zhang
