Abstract:
1. A transforming device comprising: an input terminal connectable to an external power source; a first voltage control portion that transforms a voltage at the input terminal to a voltage having a first voltage value; a second voltage control portion that transforms the voltage at the input terminal to a voltage having a second voltage value lower than the first voltage value; a switching portion capable of selecting any one of the first voltage control portion and the second voltage control portion; a current detection portion that detects a current value of a current outputted from the switching portion and controls switchover of the switching portion on the basis of a result of the detection; and an output terminal for outputting electric power outputted from the switching portion to the exterior, wherein the current detection portion compares the current value of the current outputted from the switching portion with a reference value, and in a case where the current value is equal to or higher than the reference value, the current detection portion controls the switching portion to select the first voltage control portion; and, in a case where the current value is lower than the reference value, the current detection portion controls the switching portion to select the second voltage control portion.
