    • A load driving system 1 capable of limiting the generation of an inrush current at the start of driving a load 2. A power source 3 having an output voltage higher than a normal driving voltage of the load is used for driving the load. An FET 4 is connected to the load. A rectangular pulse signal is supplied to the gate of the FET from a pulse generator 5a. The signal causes the FET to switch on and off, supplying the current to the load. When an inrush current flows at the start of driving of the load, an integrator 10 provided to the gate of the FET is operated to mitigate the rising characteristics of the pulse signal. This causes the current flowing through the load 2 to rise in a relaxation curve, thereby enabling the limitation of the inrush current.
