Hybrid Modelling and Control of Power Electronics

Switched circuits in power electronics by their nature present hybrid behavior. Such circuits can be described by a set of discrete states with associated continuous dynamics. A control objective, usually regulation of the output in the face of disturbances in the continuous system, is accomplished by choosing among discrete states. We describe a hybrid systems perspective of several common tasks in the design and analysis of power electronics. A DC-DC boost converter circuit is presented as an illustrative example, and the extension of this circuit to a multiple output configuration is provided to show the favorable scaling properties and broad utility of the hybrid approach.
