Mitigating EMI for a CISPR 22-Compliant Power Solution


摘要 : System engineers dread the prospect of not passing electromagnetic interference (EMI) compliance testing at the end of a product development cycle. If this happens, it can cause a major setback to the product shipping schedule and could also trigger a costly total power re-design. This application note examines how to achieve first-pass EMI success using a well-planned power solution design that utilizes a proper filter, low EMI components, low EMI power regulator ICs, and/or low EMI power modules, along with good PCB layout and shielding techniques.
