The H-bridge-based multilevel active rectifier is an attractive topology that allows feeding of multiple de loads. The main control problem is to manage n + 1 state variables (one current plus n dc voltages) with only n switching functions. In this paper, three PI-based solutions are discussed, and the tuning of the best solution is addressed in case resonant controllers are used instead of classical integrators. Moreover, practical problems such as the implementation and the influence of phase-locked-loop systems and of analog filters (first order and Butterworth) on the measurements are discussed.
