Frequency Response Analysis of Inverter Circuit
Main Article Content
Abstract
This paper deals with analysis of steady-state processes in an inverter circuit. Since a configuration of the inverter circuit is changed processes in such a circuit are described by differential equations with variable coefficients. It is supposed that the inverter circuit changes periodically. The Lyapunov's transform, a method of expanding of a differential equation to an equation in partial derivatives and the two dimensional Laplace transform are used to find a steady-state process. The transfer function and frequency response for processes running in the inverter circuit are introduced. The steady-state process is obtained in the form of the double Fourier series. An example of an inverter is considered and a set of frequency responses is presented.
