Abstract

The interleaved boost converter with magnetic coupling is a recent DC-DC converter topology that has drawn attention for its reduced size and good voltage gain. However, for its proper functioning, a real converter has to be controlled to deal with the unavoidable imbalance of the currents. This paper compares two control techniques applied on an interleaved boost converter with magnetic coupling. Therefore, the characteristics of the selected converter, the average current control and predictive control techniques are presented. As a result, it was found that the average current controller has the characteristic of zero steady state error, in contrast, the predictive controller allows an error in the estimated variables which causes the output voltage not to be equal to the reference value. The predictive controller considers and uses the discontinuous mode of operation, but controller has a higher computational cost than the average current controller.
