WebOpen-Circuit Inductance (OCL) In Fig. 9.1 we show how a transformer behaves when we apply a square pulse to it, as opposed to applying a sine wave to it. We remember that a transformer only passes changes in voltages to the other winding, as per the induced EMF (Faraday’s/Lenz’s) law, which leads to what we call transformer action. So if ... Webthe primary winding of T1, which always starts at zero, reaches a peak set by the primary winding inductance, input voltage and on-time t1. During this FET on-time, diode D1 is reverse-biased because of T1’s secondary winding polarity, forcing all output current to be supplied by output capacitor COUT during times t1 and t3.
