Z‐source matrix rectifier [PDF]

IET Power Electronics, 2016
This study presents a novel Z‐source matrix rectifier (ZSMR). To overcome the inherent disadvantage that the voltage transfer ratio for traditional matrix rectifier (MR) cannot be more than 0.866, a Z‐source network has been combined with the MR. The proposed rectifier realises a voltage‐boost function and the Z‐source network also serves as power ...

XTE J1701-462 and its Implications for the Nature of Subclasses in Low-Magnetic-Field Neutron Star Low-Mass X-Ray Binaries [PDF]

, 2010
We report on an analysis of RXTE data of the transient neutron star low-mass X-ray binary (NS-LMXB) XTE J1701-462, obtained during its 2006-2007 outburst. The X-ray properties of the source changed between those of various types of NS-LMXB subclasses. At

Γ-Z-Source Inverters

IEEE Transactions on Power Electronics, 2013
Voltage-type Γ-Z-source inverters are proposed in this letter. They use a unique Γ-shaped impedance network for boosting their output voltage in addition to their usual voltage-buck behavior. Comparing them with other topologies, the proposed inverters use lesser components and a coupled transformer for producing the high-gain and modulation ratio ...

Controlled Energy Flow in Z-Source Inverters

Energies, 2021
This paper proposes a method to reduce the output voltage distortions in voltage source inverters (VSI) working with impedance networks. The three main reasons for the voltage distortions include a discontinuous current in the coils of the impedance ...

Coupled Inductor Assisted High-Voltage Gain Half-Bridge Z-Source Inverter

IEEE Open Journal of the Industrial Electronics Society, 2023
A half-bridge-based impedance-source inverter with two T-shaped coupled inductors is proposed in this article. Unlike the conventional half-bridge structure, the proposed topology can generate a zero-voltage level at its output stage. First, the proposed

Sigma‐Z‐source inverters [PDF]

IET Power Electronics, 2015
To increase the boost capability with minimum passive components, existing transformer‐based Z‐source inverter (ZSI) topologies require the turn ratio to be increased. This results in larger transformer windings to be used in high dc–ac voltage gain applications.
