Multiple Hybrid Outputs for Integrated Energy Systems: Design, Control and Real‐Time Validation

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT This paper presents hybrid quasi‐Z‐source converters (qZSCs) designed for integrated energy system‐based microgrid applications, capable of providing dual‐DC and multi‐AC outputs from a single DC input source. Microgrids rely on diverse renewable energy sources such as solar and effective power converters and are crucial for integrating these ...

Effect of Parasitic Components in Voltage Drop and Design Consideration of the Switched Impedance Inverter

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
This paper examines the influence of parasitic components on voltage gain degradation and, by employing a non‐ideal impedance source inverter model, computes the voltage and current relationships of all elements. The requisite duty cycle to offset the voltage sag can be ascertained once the voltage drop is quantified.

Improved Step‐Up Z‐Source Inverter Based on Symmetric Switched Capacitor and Inductor

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
This paper introduces a novel Z‐source inverter topology with a capacitor‐assisted inductor network, achieving higher voltage gain and reduced capacitor voltage stress compared to conventional Z‐source inverters. By replacing the diode with a capacitor, it enables multiple operational modes and enhanced voltage gain, supported by steady‐state analysis,

Improved Deadbeat Algorithm‐Based Sequential Model Predictive Control Strategy for QZSI‐PMSM System

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
Aiming at the issues of the conflict between the modulation coefficients on both sides and many weighting coefficients in the cost function when all control variables are considered in model predictive control (MPC) for the quasi‐Z‐source inverter‐permanent magnet synchronous motor (QZSI‐PMSM) system, an improved deadbeat algorithm‐based sequential ...

Low‐computation‐burden model predictive current control for the grid‐tied quasi‐Z‐source inverter

IET Power Electronics, Volume 17, Issue 1, Page 10-24, 7 January 2024.
The proposed low‐computation‐burden model predictive current control greatly reduces the computational burden and eliminates weighting factors. Abstract The appealing design known as the quasi‐Z‐source inverter (qZSI) can function in both buck and boost modes. In the meantime, model predictive control (MPC) for power transformers has attracted a lot of

Analysis of Different PWM Techniques for Enhanced Ultrahigh Gain Z‐Network Topology

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
In these modern times, the Z‐source inverters (ZSIs) have become a revolutionary invention ever since the year 2002. The pulse‐width modulation (PWM) technique used for most of the ZSIs is simple boost control PWM (SBC‐PWM), and the SBC‐PWM implies for a greater voltage stress on the inverter bridge and provides less boost factor.
