摘要
分析了交错式PFC控制算法的基本原理及两相交错式PFC的优势,建立了非对称两相交错式PFC的仿真模型,并得到其仿真电压电流波形,针对仿真模型中由于元器件差异导致两相电流不相等的情况,提出了一种电流补偿控制策略。仿真结果表明补偿后的两相电流相等且输出电压稳定。
The principle and advantages of two phase interleaved PFC control algorithm is analyzed, then simulation model of the dissymmetrical interleaved PFC is established and the current and voltage waves are derived from this model; final ly,a control strategy of avoiding the different component which can bring the current unbanlance is proposed. The simulation results indicate that there is no different between two phase currents and the output voltage is steady.
