A buck converter with an LC output filter is run in a continuous conduction mode. The
inductor is finite but capacitor can be considered very large for this analysis. The
following is also known about the circuit;
ALL = 0.4 A (inductor current ripple)
6 - 25 KHz (switching frequency)
a) For Ro = 2.5 0, what is the maximum inductor current?
i) 5+0.4.2.5
ii) 5 0.4
