Abstract


Power electronic products widely used on the grid causing serious harmonic pollution . This makes the power factor correction technology to become one of the hot power electronics . Since the nineties , power factor correction technology has made considerable progress made ??many novel power factor correction theory and topology. With high-speed , low-cost digital signal processors, digital control and power factor correction techniques provide the latter with a more powerful means and methods. In this paper, Boost power factor correction circuit technologies are analyzed and studied. The first chapter is an introduction, describes the power factor correction technology and the development of digital signal processors , explains the research background and purpose. The second chapter is divided into two parts, one is the inductor current discontinuous mode power factor correction technology , analyzes its working principle, derived DCM constraint relations and inductance parameter design formulas based on MC56F8013 chips produced a prototype ; its Second, by the analog control chip to achieve the critical continuous mode power factor correction methods for the design and experimental verification . The third chapter introduces the development and generation DSP chip DSP chips used in this paper the basic properties , described in detail by this chip digital power factor correction technology and methods, and experimental verification . The fourth chapter focuses on DSP-based soft- switch with power factor correction technology , and gives experimental results and analysis . Finally, the fifth chapter is the full text summary , summed up the whole issue of research and propose further work envisaged .
