摘要： 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 1st power supply and a second delay time when the test signal is received by the Mth power 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 Mth power supply waits for the difference time to execute the first command after receiving it.
