Patent number: 10897832Abstract: A fan control system includes a fan and a target device. The fan control system includes a controller to control the rotation speed of the fan. The controller controls the rotation speed according to a time-variable rate of current consumed by the target device. Particularly, when the time-variable rate of current exceeds a threshold, the controller controls the fan to operate at a maximum rotation speed.Type: GrantFiled: August 7, 2018Date of Patent: January 19, 2021Assignee: International Business Machines CorporationInventors: Jenseng J S Chen, Jung-Tai Chen, Tsung-Yu Chen, Edward Yu-Chen Kung, Tzongli Lin, Bruce A.

Patent number: 9513684Abstract: A power supply system for maintaining the efficiency of an AC/DC power conversion unit in relation to a load is disclosed. The load varies in response to power usage during operation of the power supply system. An AC power input and a DC power output of the power conversion unit direct DC power to attached components. A master controller disposed in the power supply system detects the load of an attached computer system through a DC meter and executes an algorithm to determine the values of circuit parameters of conversion circuits in the AC/DC power conversion unit. The master controller sends the values to a mode controller through a digital signal interface. The mode controller adjusts the operating mode of the conversion circuits and thus changes the efficiency of the AC/DC power conversion unit.Type: GrantFiled: November 25, 2014Date of Patent: December 6, 2016Assignee: International Business Machines CorporationInventors: Jenseng Chen, Jung-Tai Chen, Tzongli Lin, Yu-Chen Lin, Bruce A.
