一种Boost型APFC控制芯片的设计与实现
Design and Implementation of Boost Type Active Power Factor Correction Controller IC
摘要
Abstract
A boost type active power factor correction controller based on the critical mode control technology was proposed to restrain harmonic currents and improve the efficiency of electrical power. A total harmonic distortion optimizer circuit was specially integrated to solve the crossover distortion problem that input current is zero. And a voltage feedback circuit with two over-voltage detection modes was designed to achieve fast instantaneous response and unexpected protection. A chip, with an area of only 1.36 mm2, was fabricated by the CSMC 0.5 μm BCD process. A 80 W APFC circuit was constituted based on the chip. The test results under a full load show that the measured power factor is 0.997, the total harmonic distortion of input current is 3. 1% and the efficiency is 96. 8% to prove that the chip achieves the function of power factor correction.关键词
