Abstract :
For pt.I see, ibid., vol.4, p.160-165, (2004). In this paper we will discuss the computational aspects of the frequency response power function for open loop and closed loop converter systems. The mathematical aspect of frequency response power has been discussed in detail in first paper of this two-parts paper. One important aspect of frequency response power function is that it can used to predict system sensitivity even beyond half of the switching frequency, hence it is a natural extension of frequency response of converter systems defined in classical way. We will also demonstrate the usefulness of the frequency response power function by applying it to several examples
