Abstract: A fan starting method including following steps is provided. A fan module including a control unit and a fan is provided, wherein the control unit and the fan are electrically connected with each other. An electric power is supplied to the fan module, wherein the electric power drives the fan to rotate at a full speed. Whether the fan rotates is determined by the control unit within a predetermined time. If the fan rotates, the fan is controlled to rotate at a predetermined load speed after the predetermined time. If the fan does not rotate, an alarm signal or an off signal is issued by the control unit.

Abstract: A power supply apparatus is provided. The power supply apparatus includes two power suppliers coupled in parallel so as to simultaneously supply the electric power required by an electronic product in operation. The power supply apparatus provided by the invention may stably/accurately output the desired DC output voltage to the electronic product, and may further in advance increase a main power generated inside the other power supplier when one of the power suppliers is over voltage, thereby avoiding an oversized voltage drop from occurring in the DC output voltage.

Abstract: An adapter connection structure, which includes a first converter and a second converter. The first converter is connected to at least one input terminal to receive an input power and converts the input power into a transitional power. The second converter is connected to the first converter via a transit cable to transmit the transitional power, converts the transitional power into a DC output power and outputs the DC output power via a DC power cable. As the transitional power transmitted from the first converter to the second converter is in the form of a high-voltage and high-frequency AC power or a high-voltage DC power, the power transmission loss in the transit cable is reduced. Therefore, the present invention reduces transmission loss.

The second converter is connected to the first converter via a transit cable to transmit the transitional power, converts the transitional power into a DC output power and outputs the DC output power via a DC power cable. As the transitional power transmitted from the first converter to the second converter is in form of a high-voltage and high-frequency AC power or a high-voltage DC power, the power transmission loss in the transit cable is reduced.
