摘要： The present invention discloses a method for controlling power supplies, each of M power supply has a first end and a second end, the first end of the ith power supply is connected to the second end of the (i−1)th power supply. The method comprises the following steps. A testing procedure is performed by each of the M power supplies for determining whether the first end and the second end are connected or not. A first connection status code is set when the testing procedure determines that the first end is connected, and the second end is not connected. A second connection status code is set when the testing procedure determines that the first end and the second end are both connected. A third connection status code is set when the testing procedure determines that the second end is connected, and the first end is not connected.

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.
