  • Abstract   Along with the advanced technology, the rapid development of the computer, the requirement of the high power quality that is provided by power supply is higher and higher. For satisfying these need, it is worth studying issue that how to design a switching power supply with high power factor furnishing the best electricity quality. Therefore, the exaltation of power factor and improvement of the input source of electricity is the research point of this thesis.
      In this thesis, a FAIRCHILD SEMICONDUCTOR power factor controller ML4812 is used to implement the peak current control method of the system based on boost converter for the purpose of achieving the stable voltage and high power factor of the system. Furthermore, the Hall current sensor is replaced the current transformer in order to reduce the circuit volume and cost. The input is the utility power, and the stable output of the DC voltage is 180V. The experimental results justify the performance of the power factor correction in high power applications.
