资料介绍

在半桥逆变电路拓扑中加入有源滤波电路,建立基于该滤波电路的电路分析模型,设计了电压、电流双环控制回路,探讨了基于此电路架构抑制BUS电压纹波技术。仿真结果表明在有滤波电路比没有滤波电路的情况下,BUS电压纹波降为原来的三分之一左右,实验结果显示在该情况下BUS电压纹波减小了约一倍,理论和仿真结果均验证该滤波电路的适用性。

In this paper, one type of active filter circuit is added into the half bridge inverter group. Relevant circuit model is established, voltage and current double control loop is also designed, The technique of suppression of BUS ripple wave is discussed based on the circuit architectare. Simulation results show that the BUS ripple voltage is decreased to about one third through the active filter circuit, experiment results show the BUS ripple voltage is decreased to one half. Both results verify feasibility of the filter circuit.
