摘要
介绍了基于有源功率因数校正(PFC)控制芯片UCC28019的高功率因数电源的设计。该电源具有电流谐波总畸变率低、功率因数高、结构简单、成本低廉等优点。
In this paper, we introduce the operation principles of UCC28019, which is used for controlling the power factor correction. Based on this controller, a power supply with high power factor is proposed. This power supply has low total harmonic distortion rate, high power factor, simple structure and relatively lower cost.
