Title Realization of Forward Converter Module By Applying Digital Current Sharing Technique
Keyword

  • Abstract In this thesis, a current sharing module based on microcontroller is implemented to achieve current sharing for two paralleled power converters. The used two-stage system consists of a power factor corrector and two paralleled forward converters, which not only promote the power factor, but also incorporate with a digital current sharing module to provide the required load current. The proposed digital current sharing module is made up of a microcontroller, a digital to analog converter and a LCD module. By using the SPI interface, the microcontroller can communicate with the digital to analog converter to adjust the duty cycle of each converter for current sharing by simple operation rules. Finally, we compare the practical experimental results with and without adding the proposed digital current sharing module, respectively. It is obvious that the current-sharing error rate is below ±2% by using the proposed digital current sharing technique. All the experimental results are used to verify the feasibility and validity of the proposed system.
