A generalized methodology for obtaining the steady-state solution of a closed-loop power converter

In this paper, a generalized and systematic methodology is proposed to solve a closed-loop converter system. The methodology involves two steps. First, one will identify where the loop would be broken. Then, one locates the unknown variables to be solved and formulates the corresponding iterative algorithm. The proposed method uses a top-down approach to obtain the steady-state solution of a closed-loop system, and it can be viewed as a generalized method, which embraces the previously proposed time-domain, frequency-domain and hybrid methods.
