EVL6563S-400W演示板实现了一个功率因数校正（PFC）预调节，提供连续400 W的功率在一个稳定的400 V电压轨的宽范围电源电压，并提供对电源谐波的减少，从而与欧洲标准EN61000-3-2和日本标准JEITA-MITI规定。The demonstration board implements a power factor correction (PFC) pre-regulator delivering 400 W of continuous power on a regulated 400 V rail from a wide-range mains voltage, and providing for the reduction of the mains harmonics, thus complying with the European norm EN61000-3-2 and the Japanese norm JEITA-MITI. This rail will be the input for the cascaded isolated DC-DC converter that will provide the output voltages required by the load.The board is equipped with enough heat sinking to allow full-load operation in still air. With an appropriate airflow and without any change in the circuit, the demonstration board can easily deliver up to 450 W.AN2994 Application note 400 W FOT-controlled PFC pre-regulator with the L6563S
