CMV reduction in a three-to-seven phase direct matrix converter using SVPWM
Rahman K.; Al-Emadi N.; Al-Hitmi M.; Iqbal A. ( Institution of Engineering and Technology , 2019 , Article)The pulse-width modulation (PWM)-controlled modern electric drives causes some serious problems such as the generation of common-mode voltage (CMV) and high dv/dt. The CMV might cause high-frequency leakage currents that ... -
Common mode voltage reduction technique in a three-to-three phase indirect matrix converter
Rahman K.; Al-Emadi N.; Iqbal A.; Rahman S. ( Institution of Engineering and Technology , 2018 , Article)In this study, common mode voltage (CMV) reduction using space vector pulse-width modulation (SVPWM) technique is proposed for a three-phase induction motor drive fed by a three-to-three phase indirect matrix converter ... -
Electrolytic capacitor-less dual buck inverter with CM and DM active resonance damping control for Non-isolated grid-connected PV applications
Khan A.; Ben-Brahim L.; Gastli A.; Al-Emadi N. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)The shoot-through problem of conventional H-Bridge inverters imposes a threat to system's reliability and efficiency. This is because the unintentional shoot-through state short-circuits the DC-Link capacitor. To overcome ... -
Mitigation of voltage imbalance in power distribution system using MPC-controlled packed-U-cells converter
Ahmed I.; Al-Emadi N.; Gastli A.; Ben-Brahim L. ( John Wiley and Sons Ltd , 2019 , Article)Delivering high power quality in single-phase distribution has witnessed more challenges especially with the increased penetration of single-phase distributed generation (DG). This paper proposes a smart solid-state-based ... -
A New Low Cost Linear Resolver Converter
Ben-Brahim, L.; Benammar, M.; Alhamadi, M.A.; Al-Emadi, N.; Al-Hitmi, M.A. ( IEEE , 2008 , Article)A new low cost converter topology is proposed for sinusoidal position encoders. The converter enables determination of the angle from the sine and cosine signals of the encoder. When used with resolvers, the implementation ... -
An open-loop technique for angle determination from position encoders
Benammar, M.; Ben-Brahim, L.; Alhamadi, M.A.; Al-Emadi, N.; Al-Hitmi, M. ( IEEE , 2008 , Conference Paper)The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ... -
Real-Time Fault Detection and Identification for MMC Using 1-D Convolutional Neural Networks
Kiranyaz S.; Gastli A.; Ben-Brahim L.; Al-Emadi N.; Gabbouj M. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Automated early detection and identification of switch faults are essential in high-voltage applications. Modular multilevel converter (MMC) is a new and promising topology for such applications. MMC is composed of many ... -
A resolver converter based upon a novel open-Loop Technique
Benammar, M.; Ben-Brahim, L.; Alhamadi, M.A.; Al-Emadi, N.; Al-Hitmi, M. ( IEEE , 2008 , Conference Paper)The paper presents a novel technique for the determination of the angle from slowly-varying quadrature co-sinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ... -
A weighted real-time predictive controller for a grid connected flying capacitors inverter
Ben-Brahim, L.; Trabelsi, M.; Ghazi, K.A.; Al-Emadi, N. ( Elsevier , 2013 , Article)This paper proposes a new controller for a grid connected power conditioning unit (PCU). The PCU consists of a flying capacitors inverter (FCI) connected to the grid through an inductor and a step-up transformer. A hybrid ...
