Siddique, Marif Daula; Mekhilef, Saad; Shah, Noraisyah Mohamed; Sathik Mohamed Ali, Jagabar; Meraj, Mohammad; Iqbal, Atif; Al-Hitmi, Mohammed A.... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Based on the concept of switched-capacitor based multilevel inverter topology, a new structure for a boost multilevel inverter topology has been recommended in this paper. The proposed topology uses 11 unidirectional ... -
A Single DC Source-Based Three-Level Inverter Topology for a Four-Pole Open-End Winding Nine-Phase PPMIM Drives
Reddy, B. Prathap; Meraj, Mohammad; Iqbal, Atif; Keerthipati, Sivakumar; Al-Hitmi, Mohammed ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)This article proposes a three-level inverter topology for nine-phase pole phase-modulated induction motor (PPMIM) drives by using the two identical voltage profile coils (IVPC) of a four-pole stator winding. In general, ... -
Control and modulation of three to asymmetrical six-phase matrix converters based on space vectors
Al-Hitmi, Mohammed A.; Rahman, Khaliqur; Iqbal, Atif; Al-Emadi, Nasser ( Korean Institute of Power Electronics , 2019 , Article)This paper proposes the modulation and control of a three-to-six-phase matrix converter with an asymmetrical six-phase output. The matrix converter (MC) outputs consist of two sets of three-phase spatially shifted by 300, ... -
A new angle determination method for resolvers
Ben-Brahim, Lazhar; Benammar, Mohieddine; Alhamadi, Mohd; Al-Emadi, Nasser; Al-Hitmi, Mohammed ( IEEE , 2008 , Conference Paper)A new low cost method for converting the amplitudes of the sine/cosine signals generated by the resolver into a measure of the angle of its shaft. The new method operates without lookup tables (LUT), and takes advantage ... -
New Switched-Capacitor based Boost Seven-Level ANPC (7L-ANPC) Boost Inverter Topology
Iqbal, Atif; Daula Siddique, M.; Al-Hitmi, Mohammed; Mekhilef, Saad ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)The major issue with the three-level active neutral point clamped (ANPC) topology has been the necessary use of higher DC-link voltage with lower peak across the load. In this paper, a new 1.5 voltage gain 7L-ANPC topology ... -
Performance Analysis of a Three-to-Five Phase Dual Matrix Converter Based on Space Vector Pulse Width Modulation
Rahman, Khaliqur; Iqbal, Atif; Al-Hitmi, Mohammed A.; Dordevic, Obrad; Ahmad, Salman ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)In this paper, space vector pulse width modulation (SVPWM)-based algorithms for a five-phase open-end load fed from dual matrix converter (DMC) have been proposed. In the presented modulation methods, the reference output ... -
