Chapter 13

EMI and EMC Issues

Abstract

This chapter discusses electromagnetic interference and electromagnetic compatibility. Switch regulators produce radio frequency signals because they switch at high frequency. Ringing and harmonics can extend to several hundred megahertz. Methods of reducing signals at source are discussed, with the side effects that this suppression causes. Filtering and screening are also discussed.
