Research on MATLAB Simulation of Three Level Power Amplifier for Magnetic Bearing

For FPGA-based three level switching power amplifier, this paper completed full-bridge circuit model and the current sampling circuit model was created by using Power System Blockset (PSB) library in the MATALB/Simulink. Through embedded MATLAB function file, we simulated the internal FPGA data processing. Simulation and experimental results verified the correctness of this method of modeling. And this provided a new accurate method of simulation for digital power amplifier.
