摘要
Abstract
In terms of the inadequacy of the traditional Boost-type PFC power switching devices which brings a lot of switching losses and conduction losses, and burdens with a high voltage, strong current and thermal stress, this paper proposes a new Bridgeless Topology Active Power Factor Correction (BLPFC) circuit construction. This circuit changes the two diodes in traditional rectifying bridge legs into IGBT, and adopts dual closed-loop average current control strategy to improve power factor and reduce the harmonic pollution from the grid. It can improve the system switching devices efficiently and reduce system heat dissipation and costs. This circuit is simulated using the SimPowerSystems kit in Matlab/Simulink software. Simulation results show that BLPFC provides a high efficiency, low switching losses, and can restrain current harmonics, and the input current which can keep track of the input voltage waveform well.关键词
