PROBLEM TO BE SOLVED: To provide a control device capable of detecting properly disconnection of one end to which a voltage is outputted from a transformation circuit, and to provide a transformation device and a power supply system comprising the control device.SOLUTION: A microcomputer (a control device) 21 controls actuation and stop of a transformation circuit 20 that outputs a voltage from one end at a first power storage unit side, of a DC-DC converter (a transformation device) 10, and controls a voltage value outputted by the transformation circuit 20 so that a value of a current flown from the above-mentioned one end becomes a predetermined value. The microcomputer 21 calculates a differential value between a value related a voltage value Vc acquired while an operation of the transformation circuit 20 is stopped, and a value related to a voltage value Vc acquired after the transformation circuit 20 is actuated. The voltage value Vc is outputted from a connection node between resistors R2 and R3 of a voltage detection circuit 23 to the microcomputer 21. The microcomputer 21 determines whether or not the calculated differential value is equal to or greater than a differential threshold.SELECTED DRAWING: Figure 2 |
