Compensation of Calculations Duration on Converters Output Voltage in Digitally Controled Converters Based on Law of Conservation of Energy - Project "Bumblebee"

Abstract

In the paper an example of implementation of new, original DC/DC converter controlling concept is presented. It is designed to be used in regulators with DSP processors. Control device keeps energy accumulated in converter at steady level, and in this way indirectly forces required value of output voltage. To check the possibility of using this method in real life devices, regulators algorithm was analyzed with particular attention set on numerical complexity and duration of necessary calculations. Reference was a fixed-point 32-bit DSP processor designed for energy-electronics applications. Way of compensating influence of processors calculations duration on behavior of converter is also presented. Results of conducted research and analysis confirm possibility and attractiveness of using the method to control DC/DC converters.
