模型仿真算法：1）采用电压、电流双闭环控制，直接电流控制策略，电压前馈控制。2）电压外环采用PI控制。3）电流内环采用PR（比例谐振）控制。PR控制可以几乎无差跟踪正弦电流波形，稳态误差极小。4）调制策略采用双极性SPWM。5）具有PFC补偿功能，功率因数>0.999。6）畸变小，稳态时THD谐波含量约为0.44%（均值），<1%。7）仿真模型主要涉及AC单相交流电源、整流桥、L电感、R电阻、C电容、示波器、电压采集模块、电流采集模块、PLL锁相环模块、PI模块、PR模块、双极性spwm模块等。8）各个模块功能分类明确，容易理解。运行条件：输入交流电压 AC220V，输出直流电压 DC400V，负载 16kW。,核心关键词：单相PWM整流器; 比例谐 <link href="/image.php?url=https://csdnimg.cn/release/download_crawler_static/css/base.min.css" rel="stylesheet"/><link
