What are the inrush current and peak current?

    The surge current is the peak current flowing into the power supply when the power is turned on. Since the output filter capacitor is quickly charged, the peak current is much greater than steady state output current. The power supply should limit the surge levels of AC switches, rectifier bridges, fuses, and EMI filters. Repeated switching loop, AC input

    The input voltage should not damage the power supply or cause the fuse to blow.The electrical term for the peak current is the current value at the maximum load. Generally referring to the alternating current, in the stable work time, the current and time function in the figure, the peak of the sine wave is the peak current. It is also within the range of rated current.Surge current peak: that is the peak current; peak inrush current: that is RMS current.
