PURPOSE: A power supply device is provided to minimize the generation of damage due to the delay of power supply by supplying AC power after converting DC power inside a power substation when power is disconnected in the substation. CONSTITUTION: An inverter(31) outputs power after converting DC power into AC power. A transformer(32) outputs power after converting the AC power outputted from the inverter. A current transformer(CT1) detects a current supplied from the AC power source part in a substation. A static switch(33) supplies the AC power, which is supplied from the transformer, to a device. A controller(34) controls the location of the static switch to be switched when power is disconnected. |
