PROBLEM TO BE SOLVED: To provide a device capable of completely preventing generation of an inrush current upon turning-on of a power supply to a load with a simple circuit configuration without using any resistor.SOLUTION: The inrush current prevention device is connected with a switching circuit 4 having a switching element 41 and control means 42 for on-off controlling the switching element 41 between a load 1 and a power switch 3 for power supply to the load 1. The control means 42 is configured to chopper-control the switching element 41 until a steady state is reached after power-on using the power switch 3. |
