What is inrush current?

2023-07-30

This peak current is much greater than the steady-state input current due to the rapid charging of the input filter capacitor. The power supply should limit the surge level that AC switches, bridge rectifiers, fuses, EMI filter components can withstand. Switching the loop repeatedly, the AC input voltage should not damage the power supply or cause the fuse to blow.

FAQ
