Research into a Method of Forming Neutral Point Voltage in a Three-Phase Four-Wire Voltage Inverter
Energies, 2023 Three-phase four-wire voltage inverters are commonly used in energy complexes based on distributed generation sources (solar panels, wind power plants, hydrogen fuel cells) and accumulator batteries. They allow to power loads, including single-phase ones,

Invertibility and Generalized Invertibility of Time Series Models
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1980 Summary A new invertibility concept was recently introduced by Granger and Andersen (1978), generalizing the classical one for time-independent models; we show that, in the case of time-dependent models, it cannot be considered any more as a generalization.

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 ...

Virtual Oscillator Grid-Forming Inverters: State of the Art, Modeling, and Stability
IEEE transactions on power electronics, 2022 Grid-forming (GFM) inverters are dc–ac converters that regulate their ac terminal voltage and frequency in response to real-time measurements. Recent developments on GFM controls have focused on a particular dispatchable virtual oscillator control whose ...

Inverted Length-Biased Exponential Model: Statistical Inference and Modeling [PDF]
Journal of Mathematics, 2021 This research article proposes a new probability distribution, referred to as the inverted length-biased exponential distribution. The hazard rate function (HZRF) and density function (PDF) in the new distribution allow additional flexibility as well as some desired features. It provides a more flexible approach that may be used to represent many forms
