Electrical Source Conversion

Superconducting power line

One of the most basic principles of power supplies is that the user expects an ideal source. Designers of electrical equipment and electronic circuits generally assume that this type of energy supply is available. Most of us are accustomed to this idea. The electric utility grid is carefully operated to provide a sinusoidal voltage source of good quality. Student lab […]

Introduction to Power Converter Concepts


Throughout the following posts, basic concepts of the electrical energy conversion process, together with indicators of conversion quality, are introduced. We need to establish a specific set of objectives for a converter. It is important to identify performance measures to determine ether objectives are being met. How can user expectations for a power supply be translated into design goals? How […]

Summary of Power Switch Analysis

Power Switch Circuit Analysis

Switches are the key to electronic conversion of energy. Three major aspects of design – the hardware, software, and interface problems – can be defined and studied. Consider some of the major concepts covered so far: The hardware problem (build a switch matrix). Switches can be organized in a matrix. Given information about the source and the load, the switch […]
