Feed-forward Space Vector Modulation for Single-Phase Multilevel Cascade Converters with any DC voltage ratio
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Modulation techniques for multilevel converters can create distorted output voltages and currents if the DC link voltages are unbalanced. This situation can be avoided if the instantaneous DC voltage error is not taken ...

Integrated solution for induction motor control
(2002-05)
The command speed has an 'S' shape, typical in vertical operation systems. The reason for this command speed is that a soft acceleration/deceleration avoids abrupt movements in the elevator cabin, increasing the comfort ...
