“…While retaining the main features of original Z-source inverter, they also demonstrate some extra benefits. Quasi Z-source inverters are well known for the reduced passive component stress and available continuous input current [17]- [18], and the recently proposed T-source and Trans-Z-source inverters successfully further manipulate the voltage gain by employing coupled inductors with turns ratio other than unity [20]- [21]. Nevertheless, the studies inspired by the Z-source inverter concept are limited to single-stage power conversion applications.…”

“…Several pulse width modulation (PWM) control techniques have been presented, targeting at optimally implementing modified conventional PWM strategies in terms of harmonic performance [12], and increasing the voltage gain with minimized device stresses [14]- [15], respectively. Furthermore, a group of modified Z-source inverters have been proposed [16]- [21]. While retaining the main features of original Z-source inverter, they also demonstrate some extra benefits.…”

This paper presents a family of high frequency transformer isolated impedance-source (Z-source) inverters and corresponding control method for DC to AC power conversion applications. The original single-stage Z-source inverter incorporates a unique passive impedance network coupled between the inverter main circuit and power source, thus overcoming some conceptual limitations of conventional voltage-fed and current-fed inverters. The proposed isolated Zsource inverters carefully integrate the Z-source network concept into the two-stage DC-DC-AC topology, by employing high frequency transformers. While inheriting the great merits of original Z-source inverters, such as wide input range, buck and boost functions, and high reliability against EMI noises, the proposed topologies can achieve input-output isolation and higher voltage boost ratio with reduced device stresses, with transformer secondary to primary turns ratio over 1. This paper concentrates on one example of a voltage-fed isolated Zsource inverter to elaborate the detailed operating principle and control. Simulation and experimental results are presented to verify the analysis and demonstrate the new features.

“…Among various presented structures and techniques, the coupled inductor based impedance network due to its high voltage boosting ability proved to be of high interest. Some of the well-known Magnetically Coupled Impedance Sources (MCIS) can be named as T-source [2], trans-Z-source [3], Γ-source [4], and Y-source [5]. Among the magnetically coupled impedance sources, the Y-source network has special characteristics like a very high voltage gain with a small shoot-through time; in addition, it has more degrees of freedom for tuning its gain, and hence, more design freedom.…”

Magnetically coupled Y-source impedance network is a newly proposed structure with versatile features intended for various power converter applications e.g. in the renewable energy technologies. The voltage gain of the Y-source impedance network rises exponentially as a function of turns ratio, which is inherited from a special coupled inductor with three windings. Due to the importance of modeling in the converter design procedure, this paper is dedicated to dc and ac small signal modeling of the PWM Y-source converter. The derived transfer functions are presented in detail and have been verified through simulation and experimental results.

This venture "Simulat ion and Imp lementation of Γ-Z-Source Inverters" is made out of Voltage-sort Γ-Z source inverters are proposed in this letter. They utilize a remarkable Γ -mo lded impedance arrange for boosting their yield voltage notwithstanding their standard voltage buck conduct. Contrasting them and different topologies, the proposed inverters utilize lesser parts and a coupled transformer for delivering the high-pick up and regulation proportion all the wh ile. The got pick up can be tuned by changing the turns proportion γΓZ of the transformer inside the limited scope of 1 < γΓZ ≤ 2. This prompts to lesser twisting turns at high pick up, as compared to other related topologies.
