Unidimensional modulation technique for cascaded multilevel converters
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
This paper presents a simple and low computational cost modulation technique for multilevel cascaded H-bridge converters. The technique is based on geometrical considerations considering an unidimensional control region ...

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 ...

Continuous time filter design using stochastic logic
(IEEE, 1999)
Stochastic logic is based on digital processing of random pulse stream. In this paper we propose a stochastic approach to the digital implementation of continuous time filters. The similarity between probability and Boolean ...

A collection of fuzzy logic-based tools for the automated design, modelling and test of analog circuits
(IEEE Computer Society, Institute of Electrical and Electronics Engineers, 1996)
We have developed a collection of tools for the design, modeling, and test of analog circuits. Sharing a common fuzzy-logic based framework, the tools are part of FASY (Fuzzy-Logic-Based Analog Synthesis), an analog design ...
