Why output voltage is zero in Mode 2 ? It should be equal to voltage appearing across capacitor.

When the chopper is off, the inductor terminals are reversed so according to KVL, shouldn't (-VL+Vo = 0)?

@rchelipilot3581

You are correct, the inductor voltage does switch polarity during toff. However it is necessary to keep the same polarity to derive the correct equations.

Why the inductor will reverse its polarity when switch is off?

So when switch is on load will get input voltage and when switch is off load will get inductor+capacitor voltage?

Sir I am confused when the switch is OFF the VL polarity changes... In that case current director should reverse... Even if I assume current start decreasing in same direction then the Polarity of Vo will also change. Then KVL applied at 10:35 minutes is not valid. Please explain and correct me..

dude you are correct but after applying voltage sec equation we will get vo=(dutycycle*vdc) so less than vdc value and whatever he drew in vo waveform is not correct as a result of capacitor action it will be a sinusoidal in the output dc shifted with (dutycycle*vdc). If capacitor is not there what he drew is correct but with vo=d8vdc -_- Study standard textbooks like bhimbra for deep knowledge

in dc, capacitor is an open circuit. so essentially we get maximum voltage but 0 current flow as capacitor. it is a voltage storing device so that analogy makes it easier to understand i suppose :)

Mosfet is switching in a frequency On/Off Due to that That DC is not pure DC it will be fluctuating DC As shown in waveform. So it can pass from Capacitor.

that is property of inductor, It oppose the change in current.

Why reverse current Is flowing in inductor 4.47

How come Output voltage is zero we still will have out put voltage due to the inductor right and that is why, during Toff V_L = -V_O

It's difficult to charge the inductor since it's capacitance value is very low. (4:00).

@pbaemedan

The charging of the inductor is in the magnetic field by the current flow, when the current flow changes the magnetic field decreases causing a back EMF which causes the polarity change.
