摘要:

针对开关电源在传统的Boost功率因数校正电路中有着明显的开关损耗,使得电路具有较高成本和低效率。文中在传统单相Boost变换器的基础上,采纳多通道交错并联技术来进行有源功率因数校正的主电路拓扑。以三相交错并联Boost变换器为例,分析其工作过程,并通过仿真实验证明了多相交错并联Boost PFC变换器具有减小输入电流纹波和输入电感值,以及提高变换器的效率等优点。

关键词: Boost, PFC, 交错并联

Abstract:

In terms of the significant switching losses of switching source in the traditional Boost PFC circuit,the circuit has higher cost and lower efficiency.In order to solve these problems,the paper adopts the multichannel interleaving parallel technology on the main circuit topology of active power factor correction based on the traditional single-phase Boost PFC circuit.Taking the three phase interleaving Boost converter as an example,the converter's working processes are analyzed.Simulation verifies that the multichannel interleaving parallel Boost PFC converter offers less input current ripple,smaller inductance and higher efficiency.

Key words: Boost;PFC;interleaving parallel
