Abstract

In this paper, we introduce a method to analyze three-phase inverters with current control as equivalent circuits. In contrast to existing methods, both the averaged power stage model and its closed-loop controller are represented as a single unified circuit. Since the complete system can be examined as one equivalent circuit, we can glean several insights on design and operation; particularly relating to the time scales at which the controller tracks reference signals and the ability to reject disturbances. We leverage the insights afforded by this general approach to outline design strategies for controllers in both synchronous and stationary reference frames.
