Abstract: Power amplifier is one of the important elements of any attraction type levitation system. Due to the advancement in power electronics and control technology it is now possible to develop power amplifier which will have the properties like fast dynamics, large bandwidth, ability to carry large payload, energy efficient, high reliability and cost effective. Both linear and switching mode power amplifiers have been used in the field of DC electromagnetic suspension system. In this paper, different possible switched mode power circuits for both single as well as multi-magnet based electromagnetic levitation system have been discussed and a comparative study has been made of the different topologies of power amplifiers based on their structure, working principle and experimental results. In the actual work design, fabrication and testing of both single and multi-magnet based electromagnetic levitation scheme has been made as a complete project. But in this paper the main focus is on the power amplifier.
