<p>PURPOSE: A power supply device with a first power supply device and a second power supply device is provided to supply electrical energy to a lot of load pairs. CONSTITUTION: Second power supply devices(20) comprise at least two AC power controllers(22) and a voltage sequence controller(23). Terminal groups(30) comprise at least two terminals for connecting to at least one load. The terminal groups are connected to an output terminal(24) of a second power supply device. First switching member groups are allocated to one of the terminal groups respectively. The first switching member groups comprise first switching members(51,52,53,54,55).</p> |
