The photo attached is the switching volatges across a buck converters inductor, the inductor is 10 mH   if we want to have a output ripple of 1% what sixe capacitor is needed

A step-up chopper is fed with 200 V. The conduction time of the thyristor is 200 µs and the required output is 600 V. If the frequency of operation is kept constant and the pulse width is halved, what will be the new output voltage?

the time delay that must be provided by each stage in order to achieve an oscillation frequency of 5MHz, is: M₁ M₁ M Voo M₁ Vout x10%
