The traditional aging test device comprises a power distribution cabinet and a power load cabinet, during test, power supply equipment is connected with a power load unit in the power load cabinet, and the power distribution cabinet provides power for the power supply equipment. The power load unit generally uses a resistance load, and is adjusted according to the output voltage and the output power of the power supply equipment, so that the power supply equipment is placed in a full-load working state, and continuous high-temperature aging is carried out for a plurality of hours after the setting is finished. Because the high-temperature aging needs to keep constant high temperature for a long time, the energy consumption causes the work operation cost of the aging chamber to be very high, the utilization rate of the aging chamber is improved, and the cost can be well saved. For an aging device using a resistance load, in order to solve the heat dissipation problem in the aging process, a tester has to reduce the placement density of power supply equipment, so that the utilization rate of the aging test device is reduced. In addition, the harsh degree of high-temperature aging is increased, the aging time can be shortened, the utilization rate of an aging chamber is improved, and the cost is saved.
Furthermore, a power circuit, especially a switching power circuit, has a large inductance and a large capacitance, and a power device using a high voltage and a large current generates a large inrush current at the moment of switching on and off, and the inrush current is one of the main causes of device damage. In the traditional aging test method, after the power supply equipment is started and aged, the power supply equipment is shut down until the aging is finished, and the surge resistance of the power supply equipment cannot be effectively tested without detecting the on-off impact resistance of the power supply equipment.

Examples
The block diagram of the switching controller of this example is shown in fig. 2. The startup and shutdown controller of the embodiment comprises a singlechip control unit, a memory unit, a drive isolation unit and a power execution unit. The single chip microcomputer control unit is formed by taking a single chip microcomputer (89S52) as a core, the driving isolation unit comprises a photoelectric isolator and a relay, and the power execution unit is an alternating current contactor. The singlechip runs the program in the memory, outputs a control instruction, drives the relay to act through the photoelectric isolator, and the relay drives the alternating current contactor to control the power supply of the power socket on the power load cabinet, so that the on-off control of the power supply equipment is realized.

The power-on time is 3 seconds, the power-off time is 3 seconds, and the configuration time sequence chart is shown in fig. 3. If the test parameters for the port have been set, then the state of the port may be set to up.
