SMPS, short for Switch Mode Power Supplies, are electronic circuits designed to efficiently convert electrical power from one form to another. They are known for their ability to regulate and stabilize voltage levels, making them essential components in a wide range of applications. These power supplies use a high-frequency switching method to control the voltage output, resulting in less heat generation and higher energy efficiency compared to traditional linear power supplies. As a result, SMPS units are typically smaller and lighter, making them suitable for various industries and applications.
