EMC in Power Electronics

Methodical approaches in EMC design are needed to significantly accelerate the development of power electronic devices and to reduce component costs. Major challenge is the handling of the high number of parameters necessary for predicting electromagnetic effects. This contribution describes the methods, tools and simplifications making this kind of investigation possible. Starting with modelling sources of interference the conducted spreading of interference in power electronic systems is simulated. The influence of component and line placement is added in a next step by using field simulation tools and implementing the results in circuit simulation. Examples and comparisons to measurement show the feasibility and efficiency of the proposed methods.
