Descrição
Resumo:This project studies the relevance of following proper design techniques in order to have an EMC compliant PCB for small drives. Small drives usually make use of switching strategies where the highest frequencies involved are of the order of little MHz. An existing board will serve as reference. It will be redesigned in a EMC friendly way and then tested in a semi-anechoic room in order to compare emissions and see if the layout is really relevant. In order to cut down the production costs, an additional board will be designed with a different set of components with lower prices. The objective is to see how far can the production cost be lowered before having an impact on the electromagnetic behaviour. After the tests, it has been concluded that following a good design is really important even in boards without high frequency components. It is hoped that this project will inform the reader about the basics of electromagnetic emissions and how they can be reduced
