Abstract :
This paper evaluates the error in compensation due to two main limitations. The first limitation is the lagging of the compensation reference caused by the sampling and processing due to digital signal processing equipment. The second limitation is the di/dt capability of the switching converter. Models are derived to evaluate the error due to these two limitations, as well as the percentage contribution to the total ineffectivity of compensation. Experimental results confirm that the mentioned limitation that has the most detrimental effect on compensation can easily be determined with the use of the models derived in this paper
