摘要
该文建立了脉冲调宽式逆变电源完整的非线性的Simulink仿真模型及仿真研究用的占空比计算模型和可变负载模型 ;研究了电感电流不连续现象 ,负载跳变时电源的响应和反馈调节的动态过程 ,电源开始工作瞬间输出电压的建立及控制部分的调节过程 ,以及反馈电流采样取自不同信号时动态特性的差别。并以图形化方式揭示了这些动态的、线性或非线性现象的规律。
Complete nonlinear Simulink Simulation model of Pulse-width modulation inverter was established, Duty rate calculation model and alterable load model used for simulation are also established. Non-continuous phenomena of current through inductance was studied. Response of inverter when load leap, establish process of output voltage during the initial moment and dynamic process of feedback and modulation of control circuit were studied . Differences of dynamic characteristic when feedback current sampled from different signal were also studied. Rules of these linear or nonlinear and dynamic phenomena were unveiled using graph.
