Your first prototype should be up and running. Now, it’s time to check your design to ensure that it complies with local power line standards.
Before we begin, it’s important to note that most AC-DC power supplies are designed to operate from an AC wall socket. Therefore, they are subject to rigorous power consumption and power quality standards, such as IEC 62301 standby power and IEC 61000-3-2 current harmonics standards. Compliance should always be tested early in the design cycle to help you avoid future headaches
