Abstract: A power converter includes a power stage circuit, a ramp generator circuit, and a control circuit. The power stage circuit generates an output signal according to an input signal and a control signal. The ramp generator circuit generates a ramp signal according to the control signal, the input signal, and the output signal. The control circuit generates the control signal according to the output signal, a reference signal, and the ramp signal.

Abstract: A cooling apparatus includes a casing, pumping unit, and heat exchange unit. The pumping unit includes a body and housing. The body includes a wishbone-shaped indentation and lollipop shaped indentation separate from the wishbone-shaped indentation. The housing includes a wishbone-shaped flow path and lollipop-shaped flow path separate from the wishbone-shaped flow path. The body is coupled to the housing such that the wishbone-shaped indentation and the wishbone-shaped flow path define a first flow path and the lollipop-shaped indentation and the lollipop-shaped flow path define a second flow path. The pumping unit is coupled to the heat exchange chamber such that the first flow path and the second flow path is in fluid communication with the heat exchange chamber via a first end opening and second end opening, and third opening, respectively.

Abstract: A method and an electronic device for selecting influence indicators by using an automatic mechanism are provided. The method includes following steps. Raw data is obtained, where the raw data includes a body-related variable and a plurality of to-be-measured indicators corresponding to the body-related variable. The body-related variable is set as a target parameter. The body-related variable and the to-be-measured indicators are input into a plurality of validation models, and the to-be-measured indicators are sorted according an output result of the validation models to obtain ranking data. Importance of the to-be-measured indicators is calculated by using a screening condition according to the ranking data, so as to select a candidate indicator from the to-be-measured indicators. An influence indicator is determined by calculating a correlation between the candidate indicator and the body-related variable.
