Small signal modeling and analysis of synchronverters
2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC), 2015Synchronverters are inverters that mimic the synchronous generators. The synchronverter can be easily operated in both island mode and on-grid mode, which is very suitable for the Micro-grid. A new method to get the small signal model of the synchronverter is proposed in this paper.

Small signal modeling of the MOSOS capacitor
IEEE SOS/SOI Technology Conference, 2003Summary form only given. The high-frequency small-signal sinusoidal steady-state response of the 2-terminal MOSOS (metal-oxide-silicon-oxide-silicon) capacitor is solved numerically using perturbation analysis of the basic semiconductor equations. The model includes the effects of a floating semiconductor region, interface traps and nonuniform doping ...

Small-Signal Modeling for Phase-Shift Controlled Resonant Converters
IEEE Transactions on Industrial Electronics, 2021The extended describing function (EDF) method is widely used in modeling the resonant converters. This article finds that the model of the phase-shift controlled resonant converter deduced by this method might be inaccurate especially when the duty-cycle is close to 1. The reason behind it is investigated, showing that derivation of the inverter bridge

Small-signal nonlinear modeling of television IOTs
IEEE Transactions on Broadcasting, 2002The inductive output tube (IOT) is a high power vacuum tube amplifier popularly used in UHF television broadcasting. A small-signal nonlinear model is presented for the IOT. Several simplifying assumptions are made to make the proposed model more tractable mathematically. Component values are then assigned to this simplified model based on measured IOT

Small-signal modeling of graphene barristors
Physica E: Low-dimensional Systems and Nanostructures, 2015Abstract This paper presents a small-signal model for graphene barristor, a promising device for the future nanoelectronics industry. Because of the functional similarities to the conventional FET transistors, the same configuration and parameters, as those of FETs, are assumed for the model.

Small signal modeling of wind farms
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017In large power electronic systems like a wind farm, the mutual interactions between the control systems of the power converters can lead to various stability and power quality problems. In order to predict the system dynamic behavior, this paper presents an approach to model a wind farm as a Multi-Input Multi-Output (MIMO) dynamic system, where the ...

Small-signal modeling of HVDC systems
2020In this chapter, how the current control loop and the outer loops that feed to it can be analyzed via small-signal modeling was shown. Thereby, an input-admittance matrix is formed, which characterizes the behavior of the VSC-HVDC terminal as seen from the PCC. This matrix is operating-point dependent. By modeling the grid impedance as a matrix as well,

Graphical small-signal modeling based on the inductor waveform
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012A graphical small-signal modeling based on the inductor waveform is presented in this paper. Small-signal perturbation is superimposed on the large-signal inductor waveform under steady-state condition and then the output voltage variation from small-signal perturbation is calculated by equivalent circuit.
