Abstract

Digital Switched mode power supplies are nowadays popular enough to be the obvious choice in many applications. Among all set-up and control techniques, the current mode DC-DC converter is often considered when performance and stability are of interest. This has also motivated all the “on chip” and ASIC implementations seen on the market, where current mode control technique is used. However, the development of FPGAs has created an important alternative to ASICs and DSPs. The flexibility and integration possibility is two important advantages among others. In this thesis report, an FPGA-based current mode buck/boost DC-DC converter is built in a stepwise manner, starting from the mathematical model. The goal is a simulation model which creates a basis for discussion about the advantages and disadvantages of current mode DC-DC converters, implemented in FPGAs.
