Today, Switch Mode Power Supply Systems find wide usage in nearly all electronic devices - from home computers to state-of-the-art industrial machinery and equipment. SMPS technology was first introduced in the late 1990s, and it quickly became the most successful technique for supplying DC power to electronic equipment. Known primarily for its small size and high efficiency, SMPS contains all the necessary properties that make it a must-have for all industrial sectors, from Machine Tool industries, Process & Control Monitoring to Security Systems. Therefore, due to its competence, SMPS is used to provide an efficient and effective power source.
