TDA4863集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

TDA4863屬于集成電路（IC）的PFC（功率因數(shù)校正）。由英飛凌科技股份公司制造生產(chǎn)的TDA4863PFC（功率因數(shù)校正）功率因數(shù)校正 (PFC) 是用于調(diào)整交流電路中的電壓和電流之間的相位角，使之趨近于零的半導(dǎo)體器件。不同模式包括平均電流、邊界導(dǎo)通、連續(xù)導(dǎo)通、臨界導(dǎo)通、電流控制式頻率折返、不連續(xù)和不連續(xù)導(dǎo)通，開關(guān)頻率從 6 kHz 至 1.7 MHz 可調(diào)。

Description

The TDA4863 IC controls a boost converter in a way that sinusoidal current is taken from the single phase line supply and stabilized DC voltage is available at the output. This active harmonic filter limits the harmonic currents resulting from the capacitor pulsed charge currents during rectification. The power factor which describes the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently.
