• • 1. In a DC equivalent circuit model, a capacitor behaves as an open circuit. Therefore, it may seem that the effect of ????C in the above boost converter cannot be modelled in its DC equivalent circuit. Indeed, since the average capacitor current is zero, the average voltage across ????C is also zero. However, the capacitor current has a non-zero rms value and produces loss in ????C which eventually results in a fall in the average output voltage. Using this fact, find a DC equivalent circuit model of the boost converter incorporating the effect of ????C. Neglect inductor current ripple during this derivation.
