Step Up Chopper
In this chopper average output voltage is greater than input voltage. The circuit different mode of operation and current waveforms are show.
When chopper is on current flows through L and Switch sw. In Ton period inductor L stores energy and polarity of inductance voltage shown in figure. As we know inductor opposes the instantaneous change in current therefore current does not change immediately but increase increases linearly from I1 to I2. During Ton period the input energy.
