The present invention provides a method for controlling M power supplies connected in series. The method comprises the following steps. Sending a test signal by a master power supply. Recording a first delay time when the test signal is received by the 1power supply and a second delay time when the test signal is received by the Mpower supply. Selecting a maximum delay time from the first delay time and the second delay time. Calculating a difference time between the first delay time and the second delay time. When the maximum delay time is the first delay time, the master power supply waits for the first delay time to execute the first command after receiving the first command. The 1st power supply directly executes the first command after receiving it. The Mpower supply waits for the difference time to execute the first command after receiving it.

Method for controlling power supplies

An automatic test system and method are provided. The automatic test system includes at least one formation apparatus and a test fixture. The formation apparatus receives a first control command from a network and executes a test procedure according to the first control command. The test procedure includes a charging mode and a discharging mode. The test fixture is selectively coupled to the formation apparatus. During the test procedure, when the test fixture is coupled to the formation apparatus, the test fixture generates a first measurement result. The test fixture transmits the first measurement result to the formation apparatus via a wireless communication interface of the test fixture.
