单相Boost型功率因数校正电路的开环特性

Open Loop Performance of Single Phase Boost Power Factor Correctors

讨论了Boost型功率因数校正器采用开环控制的优越性与可行性 ,分析了系统的开环工作性能 ,并且给出了变换器工作于电流DCM的临界条件。

The advantage and feasibility of pure open loop control of single phase boost power factor corrector are analyzed in this paper. The boundary of CCM and DCM is also presented in this paper. Simulation and experimental results validate the analysis.
