UCC28070评估模块是一块300W,两相交错式PFC预稳压器,采用平均电流模式控制技术来达到接近单位功率因数。此评估模块演示了TI的交错式PFC控制技术。DescriptionThe UCC28070 evaluation module is a 300W, two-phase interleaved, PFC pre-regulator that uses average current mode control techniques to achieve near unity power factor. The pre-regulator was designed to operate off a universal ac line input of 85V to 265V and provides a regulated 390V dc output. This evaluation module demonstrates TI's interleaved PFC control technology.
