| 摘 要： | 为了实现高频开关电源的数字化和产品化,对数字信号处理器(DSP)控制的功率因数校正器(PFC)模块进行了研究。提出了一种稳态二次谐波补偿(SSC)算法,解决了PFC控制中存在稳态性能与动态性能之间的矛盾,可以在很大程度上增加单相PFC电压环的带宽,提高输出电压的稳定度和输入功率因数;同时,采用anti-windupPI(AW-PI)调节器较容易地实现了高频控制和输入电流的波形控制,提高了输出电压的动态性能,开关频率可达200kHz;另外,采用双Boost电路拓扑和双模式控制取得了较高的转换效率,而且,在轻载时可以取得稳定的直流输出电压。仿真和实验结果验证了控制器的有效性。 |

| Abstract: | A steady-state second-harmonic compensation (SSC) method was developed to solve the single power factor correction (PFC) contradiction between steady-state and dynamic performance. The result greatly increases the voltage-loop bandwidth which improves the output voltagestability and increases the input power factor. The anti-windup PI (AW-PI) regulator was also redesigned to improve digital signal processor (DSP) noise immunity which increases the switching frequency and power density. The design improves the dynamic performance of the output voltage and achieves a switching frequency of 200 kHz. In addition, dual-boost PFC topology and double-mode control with variable parameters areused for higher efficiency, with the double-mode control achieving stable output-voltage at light loads. Simulations and experiments show that the digital controller provides very effective control of the voltage output. |
