| 摘 要： | 以矿井直流架线正弦波逆变器为基础,分析研究了逆变器的控制性能。逆变器带不同负载时其电流特性要发生改变,为此建立了不同负载下逆变器输出的近似传递函数模型。系统阻尼偏低,输出波形质量难于控制,采用电容电流反馈控制可有效提高系统阻尼。该逆变器以PID控制为主配以电容电流反馈控制,较好地解决了正弦波逆变器带不同负载的适应性问题,提高了正弦波的输出质量。最后对系统进行了仿真分析及实验。

| Abstract: | Based on sinusoidal inverter of mine stringing DC power,the control performance of inverter are analyzed and researched.The current characteristics of inverter are changed when it driving different loads,the approximate transfer function is built up for output of inverter driving different load.The quality of output waveform is controlled difficulty because system damp is lower,the capacitor current feedback control is used for increase of damp effective-ly.The PID control is used primarily within inverter ... |
