  • A Single-Carrier-Based Pulse-Width Modulation Template for Cascaded H-Bridge Multilevel Inverters
    Publikacja

    - IEEE Access - Rok 2021

    Multiplicity of the triangular carrier signals is a criterion for the extension of sinusoidal pulsewidth modulation, SPWM, to a number of output voltage levels per phase-leg in cascaded H-bridge (CHB) multilevel inverter (MLI). Considering medium and high voltage applications where appreciable number of output voltage levels from CHB MLI is needed, commensurate high number of carrier signals in either classical level- or phase-shifted...

  • Modified SPWM Technique with Zero-Sequence Voltage Injection for a Five-Phase, Three-Level NPC Inverter
    Publikacja

    - ENERGIES - Rok 2021

    This article presents a modified sinusoidal pulse-width modulation (SPWM) scheme for a five-phase, three-level neutral-point-clamped inverter. The modulation scheme deploys a modified min–max function to inject the zero-sequence components into the reference modulating signals; hence enabling the effective utilization of the DC-link voltage. Balanced split-input DC-link voltages were achieved through further incorporation of adjustable...

  • Control strategy for the multilevel cascaded H-bridge converter
    Publikacja

    - Rok 2013

    The paper presents the control strategy for Cascaded H-bridge (CHB) converter . The converter output voltage using Space-Vector Pulse Width Modulation (SV-PWM) strategy is controlled. The DC-link voltages are controlled by appropriate choice of H-Bridges and appropriate choice of active and passive vectors.

  • Induction motor control application in high-speed train electric drive
    Publikacja

    - Rok 2013

    The chapter presents an application of induction motor mechanical speed and load torque observers in high-speed train drives. The observers are applied for a 1.2-MW electric drive with an induction motor. The goal of using such observers is to utilize computed variables for diagnostic purposes of speed sensors and torque transmission system. The concept of diagnostic system is presented in this paper, and proper criteria are proposed....

  • DC-link voltage balancing in cascaded H-Bridge converters

    In the paper a DC-link voltage balancing strategy for multilevel Cascaded H-Bridge (CHB) converter is proposed. Presented solution bases on optimal choice of active vector durations in Space-Vector Pulse Width Modulation (SV-PWM). It makes it possible to DC-link voltages control and to properly generate the output voltage vector in the case of DC-link voltage unbalance. Results of simulation and experimental researches...

  • Hybridized Space-Vector Pulsewidth Modulation for Multiphase Two-Level Voltage Source Inverter

    In space vector pulsewidth modulation (SVPWM) algorithms for multiphase two-level voltage source inverters (VSI), the components of active vectors in all orthogonal spaces have to be calculated within the processor and stored in its memory. These necessitate intensive computational efforts of the processor and large memory space. This article presents a hybridized SVPWM for multiphase two-level VSI. In this algorithm, elements...

  • Integrated Three-Level Dual-Phase Inverter
    Publikacja

    - ENERGIES - Rok 2022

    In view of reducing the number of inverter legs that provide dual-phase, three-level output voltages (as may be needed in an uninterruptible power supply), and that also provide a wide range of output frequencies (as needed in an advanced motor drive system with wide speed ranges), a three-level, dual-phase inverter topology is presented in this paper. Its three-level attribute was based on the F-type inverter topological concept,...

  • Kompensacja drgań w napędzie z silnikiem klatkowym
    Publikacja

    - Rok 2003

    W artykule zaproponowano możliwość wykorzystania maszyny elektrycznej do kompensacji drgań momentu transmitowanego do obciążenia za pośrednictwem przekładni zębatej. Redukcje drgań na wale wyjściowym przekładni uzyskano w wyniku generowania odpowiedniej składowej zmiennej momentu elektromagnetycznego w silniku asynchrownicznym. Zaproponowano wykorzystanie bezczujnikowego układu sterowania momentem kompensującym do synchronizacji...
