WebMay 17, 2024 · What is AC inrush current for a power supply? In short, the inrush current is the power surge at the input of a power supply. It occurs during a short time period, when the input capacitors charge up after the input voltage is applied. The inrush current is higher than the nominal or operational current of the power supply. WebThe Inrush Current affects the magnetic property of the core. This happens even if the transformer has no load with its secondary open. The magnitude of the inrush current depends on the point on the AC wave the … WebThis inrush current may negatively impact the service life of the smoothing capacitor, damage contacts of the power switch, or destroy a rectifier diode. Therefore, it is necessary to limit the inrush current to the SMPS.

How to Use NTC Thermistors for Inrush Current Limiting

WebMar 31, 2015 · You can estimate the peak inrush current under a no-load condition with Equation 1: V F is the forward-voltage drop of the rectifier diode and R ESR is the equivalent series resistance of capacitor C 1. With V F = 1V and R ESR =1Ω, the peak inrush current is 168A at a 120V AC input. WebInrush Current. When a transformer is initially connected to a source of AC voltage, there may be a substantial surge of current through the primary winding called inrush current. This is analogous to the inrush current exhibited by an electric motor that is started up by sudden connection to a power source, although transformer inrush is ...
