Details

Date: September 25, 2018
EMI is an essential part of power supply design. Some design practices can be implemented earlier to allow the system pass EMI test more easily. In this presentation, the source of EMI noise, EMI noise measurement setup and noise mitigation methods are discussed. Through this discussion, the power design engineer should obtain the basic concept of EMI noise and its solutions, including layout practice, the common mode and differential mode noise separation, as well as EMI filter design.
