Laboratory of Electrical Engineering and Power Electronics

A strategic regroupment
The L2EP was born thanks to the will of 4
establishments working in partnership : The
University of Science and Technology of
Lille, Arts et Métiers ParisTech, l''Ecole
Centrale de Lille, Hautes Etudes
d''Ingénieur. The idea was to bring
together, in the same laboratory, all the
activities of research in electronic
engineering.The L2EP was established in
Lille and has an international influence. The
L2EP is a major actor in its areas of research

Introduction
Dual flyback inverter (DFBI) is one of the preferred topologies for isolated low cost low power photovoltaic (PV) applications. It converts PV cells DC voltage to output AC voltage using single power stage. It is important to understand loss distribution of DFBI be able to reach efficiency limits of this topology. This paper evaluates the efficiency of DFBI based on computer simulation results worked-out by Simetrix circuit simulator.

Abstract – This paper analyzed the power loss of transformers considering the magnetic component.
For this, each winding strategy and the effect of air gap between the ferrite core have been an
important variable for optimal parameter calculation. Inductors are very well known design rules to
devise, but the performance of the flyback converter as a function of transformer winding strategy has
not been fully developed. The transformer analysis tool used was PExpert. The influence of the
insulator thickness, effect of the air gap, how the window height and variation of the capacitive value
effects the coil and insulator materials are some of parameters that have been analyzed in this work.
The parameter analysis is calculated to a high frequency of 48[kHz]. Therefore, the final goal of this
paper was to calculate and adjust the parameters according to the method of winding array and air gap
minimizing the power loss

A new PSpice dynamic fluorescent lamp model has been developed which describes the
non-linear resistance of fluorescent lamps operating at high-frequency.
The model is based on exponential approximation that represents the equivalent resistance
variation as function of power, constructed, by experimental results for several power levels.
Simulation and experimental results are presented to verify the feasibility of the model and,
moreover, and electronic ballast example using the proposed model is presented to further
demonstrate its applications
