High-Performance Predictive Control of Quasi-Impedance Source Inverter
IEEE Transactions on Power Electronics, 2017The quasi-Z-source inverter (qZSI) has attracted much attention for motor drives and renewable energy applications due to its capability to boost or buck in a single converter stage. However, this capability is associated with different challenges related to the closed-loop control of currents, control the dc capacitor voltage, produce three-phase ac ...

PWM Control of N-Phase Interleaved Active Front-End Boost Stage-Based Impedance Source Inverter
IEEE transactions on power electronics, 2022Non-isolated high gain inverters, such as impedance source inverters (ZSI), are suitable for applications with limited input dc source voltage, e.g., microinverters. High gain in these inverters is attributed to the front-end boost stage (FBS). High step-

Application of Impedance Source Inverters
2020Impedance source inverters have attracted considerable attention in power decoupling, photovoltaic/wind power generation, and motor drive in recent years, because they can obtain high step-up boost ratio in a single stage by introducing an impedance network and special modulation strategy.

A New Half-Bridge Impedance Source Inverter With High Voltage Gain
IEEE transactions on power electronics, 2019In this letter, a new half-bridge impedance source inverter (HBISI) with high voltage conversion ratio is developed. Compared with other well-known existed HBISIs (HB-qZSIs/HB-qSBIs), the proposed HBI can increase the voltage boost factor significantly ...
