Resumen:
This article presents a high-performance control strategy for a dc-dc
Z-source converter used as the excitation-driver of a Flywheel Energy
Storage System (FESS). One possible electromechanical interface for
these systems is the Synchronous Machine. Its field winding permits
direct management of the magnetization during speed variations. The
common dc-link scheme for the dc-ac armature converter and dc-dc field
converter is used to drive the FESS. A more efficient excitation system
could be obtained using a converter with boosting capabilities. The
Z-source converter in combination with the proposed multi-loop control
law can achieve the desired voltage swing and high-performance tracking
of the reference. This control algorithm makes use of the standard duty
cycle and the shoot-through duty cycle of the Z-source converter as
independent manipulated inputs. Preliminary experimental results are
presented, which show the potential of the controller for tracking
typical waveforms.
