摘要

基于新的控制方案，研制了一种新型连续导通(CCM) PFC控制器ICE1PCS01。与传统的PFC解决方案相比，新的IC不需要来自交流电源的直接正弦波传感参考信号。采用平均电流控制，达到统一的功率因数。引入了增强的动态响应，以改善负载突然跳变时的不良性能。采用独特的软启动，防止启动时涌流过大。还有各种保护装置，确保系统安全运行。介绍了集成电路的工作原理，并给出了测试结果。

A new continuous conduction mode PFC IC with average current mode control

A new continuous conduction mode (CCM) PFC controller, named ICE1PCS01, is developed based on a new control scheme. Compared to the conventional PFC solution, the new IC does not need the direct sine-wave sensing reference signal from the AC mains. Average current control is implemented to achieve the unity power factor. Enhanced dynamic response is introduced to improve the poor behavior during sudden load jump. A unique soft start is adopted to prevent high inrush current during startup. There are also various protections to ensure the safe system operation. The IC operation is described and the test results are presented.
