Design of the 300W Power Factor Correction
Abstract
The thesis discussed the design of the active power factor corrector (APFC).Various types of APFC topologies and several control schemes are also discussed and compared. Finally, bridge rectifier and boost converter based “one-cycle control” mode is adopted. The main objective is to reduce the input current harmonics and to improve power factor.
The main advantages for the proposed corrector are simple structure, high control accuracy, quick response speed, and stable control performance.
In this thesis, how to improve the AC-DC converter input current waveform,reduce electromagnetic interference and equipment capacity, reduce the harmonic components and improve power factor, improve energy efficiency in the use of electricity have been discussed. Besides, the basic principles of APFC has been in-depth analyzed, the “one-cycle control” mode is basically researched. The main results are as follows:
1. Enumerate various types of PFC, including advantages, disadvantages, and theirs application ranges.
2. Introduce the advantages of “one-cycle control” technology. Elaborate the “one-cycle control” technology in detail for the work principles of single-phase Boost structure in APFC. Derive the equations of “one-cycle control” APFC and this control is given to achieve the main control circuit and the stability conditions.
3. The analysis of the IR1150 features and its circuit design.
4. Analysis of the 300W APFC converter parameter design process in detail, based on the realization of the principle of active power factor correction, including high-frequency input capacitance, boost inductor, output capacitance in main circuit, and output voltage dividing resistor, overvoltage protection resistor divider, frequency setting etc. in control circuit.
Key Words: power factor; APFC; boost converter; one-cycle control; harmonic wave
