    Buck-Boost Inverter Functionality of Two-Phase Semi-Z-Source Converter
    (Institute of Electrical and Electronics Engineers Inc., 2018) Remya, V.K.; Parthiban, P.; Ansal, V.; Nandakumar, A.
    A two-phase semi-Z-source (SZS) inverter capable of generating sinusoidal output voltage up to two times the input voltage is discussed in this paper. The two-phase SZS inverter consists of four switches and two Z-source networks. The buck-boost functionality achieved without the presence of shoot-through phenomenon is the major advantage of the two-phase SZS inverter. In the two-phase SZS inverter structure, there are two blocks of single-phase SZS circuits. Each single-phase SZS inverter block consists of two switches and one Z-source network. In each SZS inverter block, the switches are operated complementarily. The voltage gain of the single-phase SZS circuit block is non-linear in nature and a Modified Sinusoidal Pulse Width Modulation (MSPWM) technique is employed for generating the switching pulses. The MATLAB/Simulink results are presented to demonstrate the characteristics of the two-phase SZS inverter. © 2018 IEEE.

    Design, and Hardware Implementation of Semi-Z-Source Inverter based Transformer-less Dynamic Voltage Restorer
    (Institute of Electrical and Electronics Engineers Inc., 2023) Remya, V.K.; Parthiban, P.; Nandakumar, A.; Ansal, V.; Rajkumar, K.
    In this paper, design, and implementation of a semi-Z-source inverter based topology of Dynamic Voltage Restorer (DVR) is discussed. The topology utilizes the semi-Z-source buck inverter to synthesize the missing voltage for load compensation during power quality (PQ) events. The absence of filter components, elimination of shoot-through phenomenon, reduced size and cost of the SZS inverter are some of the attributes of the proposed DVR topology. The design and the hardware implementation of the laboratory prototype of the semi-Z-source inverter based DVR is elaborated in this paper. © 2023 IEEE.
