Smps inrush current

WebIn a SMPS, the output current flow depends on the input power signal, the storage elements and circuit topologies used, ... Inrush current: Large current when mains-powered linear power supply equipment is switched on until magnetic flux of transformer stabilizes and capacitors charge completely, unless a slow-start circuit is used. ... WebA 100kVA, 440V transformer has a DC winding resistance of 0.45 ohms, Calculate the inrush current of the transformer. Apply our formula, I (peak) = 1.414 x 440 / 0.45. Inrush current in Amps = 1382 Amps. At the same time full load current of the transformer. I (A) = kVA *1000 / Voltage. Full load current in Amps = 1000 * 100 / 440 = 227 Amps.
