摘要
本文用数据采样法建立了基于移相调功串联谐振逆变器的动态模型。并在SIMULINK环境中,采用FFT算法,仿真得出了逆变器的动态频率特性。两种方法得到的模型相一致,从而说明数据采样法同样可以用于DC-AC逆变器的建模。所建的模型将为实际试验提供有力的理论指导。
The dynamic model of serial resonant inverter with phase-shift control is built by sample-data modeling.And the frequency response of this inverter is obtained using FFT via the Matlab Simulink.Sample-data modeling fitting in the inverter topologie is verified though comparison of the analytical model and simulation model.
