    Co-Authors: Muhyaddin Rawa, Marif Daula Siddique, Saad Mekhilef, Noraisyah Mohamed Shah, Hussain Bassi, Mehdi Seyedmahmoudian, Ben Horan, Alex Stojcevski
    Abstract:

    Multilevel inverters are proficient in achieving a high-quality staircase Output Voltage Waveform with a lower amount of harmonic content. In this paper, a new hybrid multilevel inverter topology based on the T-type and H-bridge module is presented. The proposed topology aims to achieve a higher number of levels utilizing a lower number of switches, direct current (dc) Voltage sources, and Voltage stresses across different switches. The basic unit of the proposed single T-type and double H-bridge multilevel inverter (STDH-MLI) produces 15 levels at the Output using three dc Voltage sources. The proposed topology can be extended by connecting a larger number of dc Voltage sources in the T-type section. The nearest level control (NLC) switching technique is used to generate gate pulses for switches to achieve a high-quality Output Voltage Waveform. In addition, a simplified way to achieve NLC is also described in the paper. A detailed comparison with other similar topologies is provided to set the benchmark of the proposed topology. Finally, experimental work is carried out to validate the performance of the proposed topology.

  • Experimental validation of new self-Voltage balanced 9L-ANPC inverter for photovoltaic applications
    Scientific Reports, 2021
    Co-Authors: M. Jagabar Sathik, Dhafer J. Almakhles, N. Sandeep, Marif Daula Siddique
    Abstract:

    Multilevel inverters play an important role in extracting the power from renewable energy resources and delivering the Output Voltage with high quality to the load. This paper proposes a new single-stage switched capacitor nine-level inverter, which comprises an improved T-type inverter, auxiliary switch, and switched cell unit. The proposed topology effectively reduces the DC-link capacitor Voltage and exhibits superior performance over recently switched-capacitor inverter topologies in terms of the number of power components and blocking Voltage of the switches. A level-shifted multilevel pulse width modulation scheme with a modified triangular carrier wave is implemented to produce a high-quality stepped Output Voltage Waveform with low switching frequency. The proposed nine-level inverter’s effectiveness, driven by the recommended modulation technique, is experimentally verified under varying load conditions. The power loss and efficiency for the proposed nine-level inverter are thoroughly discussed with different loads.

  • State-feedback-with-integral control plus repetitive control for UPS inverters
    Twentieth Annual IEEE Applied Power Electronics Conference and Exposition 2005. APEC 2005., 2005
    Co-Authors: Kai Zhang, Li Peng, Jian Xiong, Yong Kang, Jian Chen
    Abstract:

    A new control scheme featuring a combination of state-feedback-with-integral control and repetitive control is proposed for UPS inverters. A state observer is also embedded to predict Output Voltage and capacitor current needed by the state-feedback controller, based on the sensed values of Output Voltage and load current. The system exhibits high-dynamic response and near-perfect Output Voltage Waveform

  • A multilevel Voltage Source Inverter (VSI) to maximize the number of levels in Output Waveform
    International Journal of Electrical Power & Energy Systems, 2013
    Co-Authors: Krishna Kumar Gupta, Shailendra Jain
    Abstract:

    Abstract Recently multilevel inverters are gaining popularity due to reduced Voltage stress across power switches and low total harmonic distortion (THD) Output Voltage Waveform. However, device count increases with increased Voltage levels. This paper presents a novel multilevel topology which is capable of obtaining all additive and subtractive combinations of input DC levels in the Output Waveform. Though all such levels can be obtained using the proposed topology, the actual number of levels depends on the DC source arrangement. A comparison is made between proposed topology and the classical multilevel topologies on the basis of device count and number of levels in the Output Voltage Waveform. A detailed study of the proposed topology is presented through the example of a nine-level inverter. Appropriate modulation scheme is also presented. The proposed concept is analyzed through simulation studies and verified experimentally.
