摘　　要：介绍了Boost-APFC电路工作在临界导通模式下的优势。针对传统单相CRM-Boost APFC电压模式控制方法存在PI参数调试时间较长、调节效果较差、不稳定因素增加等不足,提出了一种有静态工作点的单相CRMBoost APFC电压模式控制方法,并通过PSIM仿真验证了该方法的优点。针对新型交错控制方法存在PI参数调试时间较长、不稳定因素增加等不足和需要额外使用一个电压控制电流源的情况,提出了一种改进型两相交错并联CRM-Boost APFC电压模式控制方法,并且完成了PSIM仿真,功率因数高达99.96%。制作了一台4kW的两相交错并联CRM-Boost APFC实验样机,并进行了实验调试,功率因数达到了99.66%,效率为98.02%。The advantages of a Boost-APFC circuit operating in critical conduction mode are introduced.Aimed at the disadvantages of the traditional single-phase CRM-Boost APFC voltage mode control method,such as a long PI parameter debugging time,a poor adjustment effect and increasing unstable factors,a single-phase CRM-Boost APFC voltage mode control method with a static operating point is proposed,and the advantages of this method are verified by PSIM simulations.Considering the shortcomings of the novel interleaved control method,such as a long PI parameter debugging time,increasing unstable factors and the need to use an additional voltage-controlled current source,an improved two-phase interleaved parallel CRM-Boost APFC voltage mode control method is put forward,and the PSIM simulations are completed,with a power factor as high as 99.96%.A 4 kW two-phase interleaved parallel CRM-Boost APFC experimental prototype was made,and it was experimentally debugged,with a power factor of 99.66%and an efficiency of 98.02%.
