Abstract

Electromagnetic effects have an important influence on all aspects of power electronic design. The effects of stray magnetic and electric fields on circuit performance, and the necessity to control the resulting stray inductance and capacitance by good circuit design practices are introduced. Inductors are key components and the pressure to design to meet high-frequency specifications is relentless. Four types of inductors are discussed briefly and their electromagnetic properties are compared and contrasted. High-frequency transformers are discussed in terms of their impact on circuit behavior and their major design issues. The limitations of conventional topologies at multimegahertz frequencies are explored. A circuit example of a half-bridge series-parallel resonant converter working between 1-2 MHz and implemented using hybrid technologies is used to demonstrate how circuit, component and layout design are electromagnetically interdependent
