D.C. ripple immunity testing. In electrical and electronic systems, D.C. power supplies may contain residual ripple voltage caused by rectification and power-conversion processes. This ripple can influence the operation of connected equipment. Understanding how to evaluate equipment immunity to these disturbances is an important part of Electromagnetic Compatibility (EMC) testing. This course introduces the technical concepts behind D.C. ripple immunity testing and explains how the relevant test parameters, test equipment, laboratory arrangements, and evaluation procedures fit together. Whether you are an EMC engineer, electrical or electronics engineer, test engineer, laboratory technician, compliance professional, engineering student, or beginner interested in EMC standards, this course will help you develop a structured understanding of IEC 61000-4-17.
What Will You Learn?
Throughout this course, you will explore the fundamentals of D.C. ripple immunity testing and the purpose of applying controlled ripple disturbances to the D.C. power input of equipment under test. You will learn about residual D.C. ripple voltage, its characteristics, and its relationship to rectifier systems, battery chargers, and D.C. power supply networks. You will also become familiar with important test parameters, including nominal D.C. voltage, maximum and minimum voltage levels, peak-to-peak ripple voltage, ripple frequency, and test severity levels. The course explains the role of D.C. ripple test generators and introduces the technical considerations associated with voltage capability, current capacity, waveform generation, and load performance.
