Abstract: A dual-input power switching system includes a first DC power source, a second DC power source, a DC conversion circuit, and a boost-up circuit. The first DC power source provides a first DC voltage, and the second DC power source provides a second DC voltage. The DC conversion circuit receives the first DC voltage or the second DC voltage being an input voltage, and converts the input voltage to supply power to a load. The boost-up circuit provides a hold-up voltage to boost up the input voltage when the first DC power source stops supplying power to lead to power drop of the input voltage, such that the input voltage reaches to a specific voltage that is greater than the second DC voltage and afterward naturally decreases to be less than or equal to the second DC voltage.

The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.
