摘要
针对单相电路的谐波和无功电流的检测问题,在对自适应干扰消除法进行理论推导和检测原理分析的基础上,利用半桥升压式PWM变换器主电路及直流侧电压闭环PI调节器,设计了自适应干扰消除法的一种具体实现方案,仿真结果表明了该方法的合理性与可行性。
Aiming at the detection problem of harmonic current and reactive current of single phase circuit,this paper proposes a specific realization of adaptive interference elimination based on the theoretical derivation and the analysis of detecting principle of adaptive interference elimination with making the half-bridge PWM converter as main circuit and closed loop PI modulation of DC side voltage as the control circuit.The simulation result confirms its correctness and feasibility.
