摘要
为提高功率因数和抑制谐波对公共电网的污染,设计了一套基于UC3854芯片的单相有源功率因数校正电路,同时还能够为后级负荷提供稳定的直流电压。主要介绍单相有源功率因数校正的工作原理,详细分析电路主要参数的选择和设计。通过采用PSIM仿真软件进行仿真与研究,仿真结果表明该电路设计合理、性能可靠,功率因数可提高到0.99,实现了功率因数的校正的目的。
In order to improve the power factor and harmonic suppression on the public power grid pollution, design a based on UC3854 chip single-phase active power factor correction circuit, and at the same time, it can also provide a stable DC voltage for the load. Introduce the working principle of single phase active power thctor correction, and a detailed analysis of the choice and design of main circuit parameters. By using PSIM simulation software was simulated and investigated. The simulation results show that the circuit design is reasonable, reliable performance, the power factor can be increased to 0.99, the realization of the power factor correction.
