Figure 1: Pre-charge Initial State
An inrush current, also referred to as input surge current, or switch on surge, is the high current, which is often drawn when circuits are initially switched on. Power converters can have inrush currents that are many times higher than their steady-state currents. This is due to the initial charging current of
