Study on High Performance Power Amplifier for Maglev Flywheel

Abstract:

Power amplifier for maglev flywheel control system should have the characteristics of low ripple and fast response. In this paper, a maglev flywheel and a method of two-level power amplifier based on DSP and FPGA are proposed. An equivalent model of switching power amplifier based on Fourier series is established and simulation analysis is carried on as well. Experimental platform for switching amplifier is built and experiment results show that the coil current signal can track command signal fast and stably, which proves the validity of the proposed design method. Simulation results are close to the experimental result, which means that the model can guide the power amplifier design.
