Analysis of Z-Source Inverter For Space Vector PWM Fed 3-Phase InductionMotor [PDF]

Engineering and Technology Journal, 2010
This paper presents analysis of operation and implementation of Z-source space vector pulse width modulation (SVPWM) inverter fed three phase induction motor. The Z-source is an alternative power conversion topology that can both buck and boost the input

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Switched-Inductor Extended-Boost Quasi-Z-Source Inverter

IEEE Access
This paper introduces two novel impedance source inverter topologies for switched-inductor extended-boost quasi-Z-source inverters: diode-assisted and capacitor-assisted switched-inductor extended-boost quasi-Z-source inverters.

Low-Loss Active Grid Impedance Cancellation in Grid-Connected Inverters with LCL Filter

Applied Sciences, 2019
Distributed power inverters with inductive capacitive−inductive (LCL) filters have become popular in distributed power generation system. However, due to unknown grid impedance, the inverters are confronted with challenges of local filter resonance,

A Switched Quasi-Z-Source Inverter with Continuous Input Currents

Energies, 2020
Impedance source converters as single-stage power conversion alternatives can boost and regulate the output voltages of renewable energy sources. Nevertheless, they, also known as Z-source inverters (ZSIs), still suffer from limited voltage gains and ...

A New Non-Isolated Active Quasi Z-Source Multilevel Inverter With High Gain Boost

IEEE Access, 2023
This paper proposes a three-level diode clamped active impedance source inverter (AIS-TLI) based on the quasi Z-source inverter (qZSI). Apart from having minimal components and the inherent benefits of three-level qZSIs, such as single-stage buck-boost ...

The BLIXER, a Wideband Balun-LNA-I/Q-Mixer Topology [PDF]

, 2008
This paper proposes to merge an I/Q current-commutating mixer with a noise-canceling balun-LNA. To realize a high bandwidth, the real part of the impedance of all RF nodes is kept low, and the voltage gain is not created at RF but in baseband where ...

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

Molecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Stator Current Harmonic Reduction in a Novel Half Quasi-Z-Source Wind Power Generation System

Energies, 2016
The generator stator current gets distorted with unacceptable levels of total harmonic distortion (THD) because impedance-source wind power generation systems use three-phase diode rectifiers. The stator current harmonics will cause increasing losses and
