A small-signal model of a solar cell

SIMULATION, 2014
Starting with the experience that the output voltage and the output current of a photovoltaic panel are not pure direct current constants due to the inevitable connection to a converter (or inverter) that is working as a switching system, we came to the conclusion that interest exists for the behavior of the solar cell at the frequencies of the ...

Transforming small-signal modeling into control system modeling

Proceedings of the IEEE 1998 Custom Integrated Circuits Conference (Cat. No.98CH36143), 2002
This paper describes the transformation of small-signal modeling into control system modeling. Transforming a small-signal circuit into a control system equivalent results in a behavioral signal path model. A behavioral signal path model gives insight in the operation of a circuit because it shows all the different conversions from current to voltage ...

The discrete small signal modeling of the multiresonant converter

2003 IEEE Bologna Power Tech Conference Proceedings,, 2004
The modeling and analysis of the multiresonant converter is presented. The converter is analyzed by means of state-plane diagram. The state-plane approach is used for steady state analysis as well as small signal analysis. The discrete small signal model has been derived from the state-plane graphical properties.

Small-Signal Model of LLC LED Driver

2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018
This paper presents the small-signal model of the full-bridge LLC LED driver for system analysis. By using the Taylor series model, a V-I curve lookup table is generated to model the LED. The LED array can be built by a simple equivalent circuit composed of one LED model and two dependence sources for circuit simulation.

A new SEPIC inverter: Small signal modeling

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
This paper presents a new inverter technology that is designed based on SEPIC converter. Small signal model and transfer functions of the inverter are obtained. The system demonstrates the existence of a non-minimum phase zero in positive peak and shift of that zero to left half plane to make the negative peak transfer function a minimum phase behavior.

Small-signal dynamic modeling of HVDC systems

IEEE Transactions on Power Delivery, 2002
This paper details the development of a linear continuous-time state model of the small-signal dynamics of a high-voltage direct current (HVDC) transmission system. The dynamics in the frequency range between 2 and 200 Hz on the DC side are of interest for the identification of possible stability problems and the design of the fastest level of ...

Small signal modeling and analysis of synchronverters

2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC), 2015
Synchronverters 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.
