一种新型的CRM-Boost APFC控制方法
Novel CRM-Boost APFC Control Method
摘要
Abstract
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％.关键词
