Output capacitor dissipation

For the Buck, we see that the input capacitor RMS actually maxes out at D = 50%, whereas the output capacitor RMS current (curve number 12) increases dramatically at low D (high input). Does that really mean that we have to worry about the dissipation in the output capacitor Think about it. The output capacitor in a Buck is barely responsible for any of its losses, since it sees only the smoothened (undulating) inductor current. So yes, as a... 

In order to study forced systems the concept of passivity is introduced. A passive system is a dissipative system where the net supply of stored quantity is a function of the measured outputs and manipulated inputs only [13]. The concept passivity originates from electronic circuit theory, where passive components are e.g. resistors and capacitors. 

The power factor (PF) is the ratio of power dissipated to the product of the effective power output (volts x amps) and is a measure of the dielectric loss in the insulating plastic (which is effectively acting as a capacitor). The power factor and dissipation factor are related by the equation...
