METHOD FOR CONTROLLING POWER SUPPLIES

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 1.sup.st power supply and a second delay time when the test signal is received by the M.sup.th power supply.
