Now, is dependent on both the input voltage, , and the input current, , of the MC. This dependence is expressed as

A high value of Q is actually desirable in since this implies lesser ripple component in , hence lower loss. But, a similar consideration (high Q) in indicates higher loss due to increase in low order harmonic content in . These plots exhibit response similar to that experienced with the normalized form of in Fig. 3.3. From this similarity, chosen in Sect. 3.1.1 expectedly leads to an even balance between both these conflicting aspects. Thus, the value of is finalized for the input filter.

Power loss occurring in is given by
