准PR调节下单相全桥逆变器的非线性现象研究
Study of Nonlinear Phenomena for Single-phase Full-bridge Inverter with Modified PR Controller
摘要
Abstract
Aiming at the nonlinear phenomenon of inverter,the single-phase full-bridge inverter with modified proportional-resonant(PR)controller was regarded as the research object. The discrete model of system was built by the stroboscopic map. Selecting the proportionality coefficient as the bifurcation parameter ,then the bifurcation diagram of the system was obtained,with different bifurcation parameters,numerical simulation of the output current was gained by the folded diagram. The influence of the proportionality coefficient were analysed by the bifurcation diagram and the folded diagram. The correctness of discrete model was verified by comparing the folded diagram with the result of Matlab/Simulink under the same parameters. Finally,the proportional coefficient and integral coefficient were put as a two-parameter bifurcation to get the system stability range based on the eigen value of Jacobian matrix ,which provides a theoretical basis for the single-phase full-bridge inverter with modified PR controller.关键词
