Measuring Inrush Current
4.5.1 Inrush
Current
On an electric device using a capacitor input type rectifier circuit for power input, an excessive
current in comparison to the Normal state may flow for a short period of time immediately after the
start of power supply. This current is called inrush current. If such a big current flows to the power
line, the supply voltage may drop due to the impedance of the power line. Therefore, the inrush
current is restricted below a certain level in some standards.
Figure 4-21 shows the inrush current waveform of a small electric drill. The inrush current flows at
14 A peak, which is about four times of the rated current of 3.5 A.
