Abrégé

Power timing control devices and methods are disclosed. Each of one or more controlled chips is enabled based on a logical-AND-gated operation of primary and auxiliary enable signals to generate a control voltage based on a DC power voltage. In a signal timing sequence, a representative moment during the control voltage falling from high to low level occurs earlier than a moment when a level on a signal waveform of the DC power voltage falling from high to low level equals a minimum operation voltage level for the controlled chip. In this way, a power timing control operation can be performed under both light and heavy load conditions of a system, and a controller can be driven for powering up and off the system according to the control voltage, thereby effectively preventing the controller from abnormality or breakdown.

An auxiliary production clamp including a first clamp element, a second clamp element, a pivot shaft, an elastic component and an ejector assembly for a power module and a using method thereof are disclosed. The second clamp element includes a through opening running through a second pressing end and spatially corresponding to a first pressing end of the first clamp element. The pivot shaft is pivotally connected between the first clamp element and the second clamp element. The elastic component is sleeved on the pivot shaft to provide a pressing force. The ejector assembly is provided on the second pressing end and spatially corresponding to the through opening. In a working state, the first pressing end presses against a upper first magnetic core of the power module, and an abutting end of the ejector assembly is driven to run through the through opening and push against the second magnetic core.

A centrifugal fan includes a housing and an impeller. A top side of the housing has a main air inlet. A bottom side of the housing has a holder, a board, and plural supporting ribs connecting the holder and the board. The holder, the board, and the supporting ribs define a first secondary air inlet and a second secondary air inlet. In the extending direction of the central axis of the impeller, the impeller projects an upper projection to the top side, and projects a lower projection to the bottom side. The size of the upper projection is greater than the size of the main air inlet. At least one portion of the outer edge of the first secondary air inlet, the outer edge of the lower projection and the central axis are arranged in sequence.
