Research on modeling and simulation of switching power amplifier for active magnetic bearing applications based on MATLAB

The structure and principle of a switching power amplifier for active magnetic bearing (AMB) applications was analyzed, and a method for modeling and simulation of the switching power amplifier control system in MATLAB was proposed. Based on MATLAB/Simulink using power system block (PSB), the simulation model of the switching power amplifier was derived in order to analyze the system performance. As an illustrative example of a practical switching power amplifier, numerical simulation and experimental method were implemented. The consistency of the final simulation results with the experimental results verifies the validity of the modeling method. The method also offers a new thought for analyzing the characteristics of the switching power amplifier for AMB.
