| 摘要: |
| 以单相单周期控制 Boost 结构有源功率因数校正电路为研究对象，分析了有源功率因数校正技术的基本原理，并对其稳定性进行数学分析，同时推导出了单周期控制方程。基于IR1150控制芯片，用简单的电路实现该控制，因无需乘法器和检测输入电压电路，简化了电路。针对300 W实际样机，对整个功率因数校正电路的高频输入电容、Boost电感、Boost输出电容、输出电压分压电阻、过电压保护分压电阻、IR1150 的工作频率、检测电阻及其他参数进行设计。对所设计电路进行了仿真，并对样机进行了测试，获得仿真和测试波形及测试数据。仿真结果和测试结果表明，基于单周期控制的有源功率因数校正电路功率因数达到0.99以上，谐波分量低，且电路简单。 |

| Abstract: |
| The principle of single-phase Boost APFC（Active Power Factor Correction） circuit is studied，its stability is analyzed and its one-cycle control equation is deduced. A simple control circuit based on IC IR1150 is adopted，which has no multiplier and input voltage detection circuit. Its parameters are designed for a 300 W prototype，including high-frequency input capacitor，Boost inductor，Boost output capacitor，output-voltage dividing resistors，over-voltage protection dividing resistors，IR1150 working frequency，detecting resistor，etc. The designed circuit is simulated and the prototype tested. Simulative and testing results show that，the Boost APFC circuit with one-cycle control is simple，reaches higher power factor than 0.99 and has low harmonic components. |
