    Matrix converters are direct AC/AC power converters that can operate with sinusoidal output/input voltage/currents without the need of passive components to store energy, which means that they are grid friendly and have a great weight/volume reduction potential. Hybrid power converters are arrangements of two different type of converters, a main one, processing the bulk of the power interconnected... View full abstract»

    A new modulation and control strategy for a matrix converter induction motor drive is presented in this paper. A discrete model of the converter, motor and input filter is used to predict the behaviour of torque, flux and input power of the system. The switching state that optimizes the value of a quality function is selected. The predictive control method, referred to as predictive torque control... View full abstract»

    Controlled ac drives without speed sensors of the motor shaft are in increasing demand. Eliminating the speed sensor increases the reliability of the overall system and reduces its cost. The proposed method employs electrical quantities, the stator current and stator voltage space vectors, as input signals in a closed-loop observer to estimate the rotor speed. The sensorless observer is built arou... View full abstract»

    This paper proposes a new reduced delayed-state Kalman filter (DSKF) based algorithm to realize the speed-sensorless vector control of induction motor. This algorithm estimates the stator flux components in the stationary reference frame, using the derivatives of the stator flux components as mathematical model and the stator voltage equations as observation model. The DSKF-based algorithm accurat... View full abstract»

    The paper presents a detailed sensitivity analysis comparison between two existing low-cost sensorless solutions for induction motor drives. The first solution is a V-type approach, in which the inverter voltage references are calculated from the machine equations instead of obtained as the output of PI current regulators. The scheme is obtained from a standard field oriented control drive by succ... View full abstract»

    This paper investigates a modified direct torque control (DTC) scheme based on space vector modulation (SVM) for interior permanent magnet synchronous motor (IPMSM) drives. Closed-loop control of both the torque and stator flux linkage are achieved by using two proportional-integral (PI) controllers. The reference voltage vectors are generated by a SVM unit, which replaces the switching table in t... View full abstract»

    In the photovoltaic branch, transformerless inverters are nowadays the majority of the systems installed in Europe, mainly because of the higher level of efficiency and reduced cost and weight when compared with their counterparts with transformer, whether this concerns low- frequency or high-frequency models. Nevertheless, some limitations arise for the operation of such systems, mainly regarding... View full abstract»
