“…The fundamental idea is to represent the state variables using a truncated Fourier series, in which the large ripple components can be involved in constructing averaged models. Extensions of conceptually similar approaches have been applied to other switching systems, such as converters [4], [5], inverters [6], [7] and rectifiers [8].…”

Multifrequency averaging is a generalization of the state-space averaging technique for representing converters in which large ripple may be present. Herein, a method of representing naturally sampled PWM converters using reduced-order multifrequency averaging is proposed. An associated NewtonRaphson method is developed to achieve fast convergence in simulation. The proposed method is capable of predicting the system average behavior and system stability.
