“…There are two types of digital control, which are linear control and nonlinear control. In linear control the output current is measured and then compared with the desired current reference [108] [109]. The resulting current error is then amplified using a controller block, which generates a corresponding voltage command.…”

Active magnetic bearings (AMB) have gained significant attention in recent years due to their superior performance in various industrial applications. One crucial component of an AMB system is the discrete power amplifier, which plays a vital role in driving the magnetic coils and controlling the position and stability of the rotor. This article provides a comprehensive review of power amplifier technologies in combination with the H bridge converter and feedback sensing circuits used in AMB. In addition, it discusses the design considerations, operational principles, and performance metrics of power amplifiers. Finally, challenges and potential future directions in power amplifier technology for AMB along with conclusions are highlighted.
