摘要
分析计算出Γ型中频滤波器的参数,为避免采用Γ型滤波器的逆变器在空载或轻载时,系统容易发生的扰动谐波振荡,根据分离式谐振阻尼LC滤波器的思想优化设计滤波器的结构和参数。仿真证明该滤波器可实现负载变化电源稳定,抑制振荡,输出电压波形质量较高。
The parameters of Г intermediate-frequency filter is analysed.When the system of inverter with Г-filter is in idle circuit condition ,the system can protect from the perturbation harmonic vibration.The structure and the parameters of Г-filter are optimum designed according to separate resonance damping LC-filter.At last,the simulation is given to prove that a inverter with Г-filter is stable when the load changes, and the voltage waveform is high quality.
