Power supply regulations, requirements, and standards
Regulatory standards cover safety and electromagnetic compatibility (EMC) and efficiency. Safety and EMC standards are relatively straightforward, and their numbers are limited. Efficiency is a different matter: Society’s drive to reduce greenhouse gas emissions results in increasingly sophisticated energy efficiency standards for all types of power converters. It started with relatively simple ENERGY STAR standards […]
