摘要
功率因素校正技术(PFC)是为了达到使输入电流波形跟随输入电压波形,减少电网电压谐波畸变,提高电能利用率等目的而发展起来的技术,目前已经广泛应用于家用电器领域^([1])。本文通过使用TI公司PFC专用集成芯片UCC2818芯片和单片机实现了一种运用软件进行电压跟随的PFC方案,分析了该方案的原理,并给出了测试结果。结果表明,这种方案使用简单、灵活,运行更加可靠。
In order to make the current waveform follow the input voltage waveform,reduce the power grid voltage harmonic distortion and improve energy utilization,Power Factor Correction(PFC) technology was gradually developed and widely used in the field of household appliances.In this paper,by using the TI company's special integrated PFC chip and microcomputer realized a voltage follower PFC scheme which used the made-up software algorithms,we analyze the principle of this scheme and gave the test result.The result shows that this scheme is more simple,flexible and reliable for using.
