Abstract: An energy-saving power supply apparatus includes a bridge rectifier, a diode bypass circuit and a control circuit. The diode bypass circuit is electrically connected to the bridge rectifier. The control circuit is electrically connected to the diode bypass circuit and the bridge rectifier. The bridge rectifier includes a plurality of diodes. After the control circuit receives a power start signal, the control circuit is configured to control the diode bypass circuit, so that a part of the diodes are bypassed to save energy.

Abstract: A power supply detection apparatus including a base, a couple of longitudinal motion mechanisms, a couple of lateral motion mechanisms, a couple of pin bases and a couple of vertical motion mechanisms is provided. Each lateral motion mechanism is movably arranged on the corresponding longitudinal motion mechanism and thereby driven to move horizontally. Each pin base is driven to move horizontally by the corresponding lateral motion mechanism and a probe is arranged on each pin base. The probe and the perpendicular lateral motion mechanism are moved along respective directions perpendicular with each other. Each vertical motion mechanism is arranged on the corresponding pin base for driving the probe to move vertically. The probes can be thereby moved to automatically detect an electric power status of an electronic component on a circuit board of a power supply.

Abstract: An over voltage protection testing apparatus is applied for testing an over voltage protection function of a power supply apparatus. The over voltage protection testing apparatus mainly includes a voltage boost-storage unit and an energy release unit. The voltage boost-storage unit boosts an original output voltage outputted from the power supply apparatus into a testing voltage. Therefore, no extra testing voltage source is required for testing the over voltage protection function of the power supply apparatus. Moreover, the extra energy would be released to the energy release unit after the testing of the over voltage protection function of the power supply apparatus is finished. Therefore, the energy releasing of the present invention is faster than the energy releasing of a related art.
