摘要
以城轨地铁牵引供电系统中网侧BoostPFC电路为研究对象,采用单周期控制技术,对单周期控制技术原理进行分析,给出单周期控制的BoostPFC电路数学模型和控制方程,最后在Pspice下建立仿真模型,仿真波形表明单周期控制是一种简单有效的控制方式。和传统控制方法相比,单周期控制不需使用乘法器或高速数字器件就可以提高交流侧功率因数,同时直流侧还有稳定的直流电压和动态响应。
In this paper, a solution for one-cycle control(OCC) based Boost PFC is analyzed. The control method is simplified; therefore the circuit is also of a simplified structure with high reliability. The completely hardware-based circuit is designed and implemented, while the simulation model in Pspice is given. In the author's practice, the power factor of OCC-based Boost PFC circuit is extremely approaching unit when the DC side is getting stable voltage with a sensible dynamic response.
