摘要
研究了电压型网侧变换器的原理,建立了在两相旋转坐标系下数学模型、设计出了控制策略、进行了仿真分析。并通过仿真验证了网侧变频器具有输入输出特性好、谐波少、能量可双向流动等特点。
The grid-side converter principle was researched. The mathematical model was established in the situation of the two phase rotating reference frame. The control strategy was given. The result of simulation was analyzed. And through simulation show that gridside converter is advantageous in high power factor, small input-line current harmonic distortion and bi-directional power flow.
