| dc.description | The use of controlled power converters has been extended for high power applications,
stacking off-the-shelve semiconductors, and allowing the implementation of, among others, AC
drives for medium voltages of 2.3 kV to 13.8 kV. For AC drives based on power cells assembled
with three-phase diode rectifiers and cascaded H-bridge inverters, a sophisticated input multipulse
transformer is required to reduce the grid voltage, provide isolation among the power cells, and
compensate for low-frequency current harmonics generated by the diode-based rectifiers. However,
this input multipulse transformer is bulky, heavy, and expensive and must be designed according to
the number of power cells, not allowing total modularity of the AC drives based on cascade H-bridges.
This study proposes and evaluates a control strategy based on a finite control set-model predictive
control that emulates the harmonic cancellation performed by an input multipulse transformer in a
cascade H-bridge topology. Hence, the proposed method requires conventional input transformers
and replaces the three-phase diode rectifiers. As a result, greater modularity than the conventional
multicell converter and improved AC overall input current with a THD as low as 2% with a unitary
displacement power factor are achieved. In this case, each power cell manages its own DC voltage
using a nonlinear control strategy, ensuring stable system operation for passive and regenerative
loads. The experimental tests demonstrated the correct performance of the proposed scheme. | |
