可编程输出功率因数预调节器 PROGRAMMABLE OUTPUT POWER FACTOR PREREGULATOR
DESCRIPON
The UCC2819A/UCC3819A provides all the functions necessary for active power factor corrected preregulators. The controller achieves near unity power factor by shaping the ac-input line current waveform to correspond to that of the ac-input line voltage. Average current mode control maintains stable, low distortion sinusoidal line current.
