Analysis, Simulation and Hardware Implementation of Single Switch Power Amplifier for Active Magnetic Bearing (AMB) system

Sukanta Debnath, Pabitra Kumar Biswas, Jonathan Laldingliana


Active Magnetic Bearing is the advancement of habitual technology and is used to increase the rotational speed. AMB is using power electronics drives, which is the key features of this technology. In this paper, a simple and cheap converter with reduced switch is simulated and implemented in hardware for the validation of simulation result is presented. The principle of the active magnetic bearing and power amplifier is introduced and the generation of pulse is also described. Then, result of simulation and hardware output is compared. Based on the output of hardware setup simulation result is validated. With the help of this amplifier cheapest and better control for active magnetic bearing can be achieved.
