Design of Transformer and Power stage of Push-Pull Inverter








Design of Transformer and Power stage of
Push-Pull Inverter

Milomir Šoja, Slobodan Lubura, Dejan Jokic, Milan D. Radmanovic, Goran S. Dordevic,
and Branko L. Dokic
Abstract—In this paper is presented the example of
construction of push-pull inverter that can be used in two
different topologies, with two input voltages and three
power ratings which can at the same time achieve AVR
function and “power-save” feature. Special attention was
paid to scheme, turn ratio calculation and transformer coil
windings arrangements that with only two types (of
different power ratings) allows realization of large number
of push-pull inverter configurations that can be applied to

Design and Realisation of Over-voltage Protection in Push-pull Inverters


Design and Realisation of Over-voltage
Protection in Push-pull Inverters
Milomir Šoja, Slobodan Lubura, Dejan Jokic, Milan D. Radmanovic



Abstract—In this paper are presented our research results
about possibility of use different types over-voltage protection
circuits in push-pull inverters. We first analyzed the conventional
passive type RC and RCD over-voltage protection circuits and
gave experimental results. After that we analyzed active overvoltage
protection circuit, made design of protection circuit
components and provided experimental results. Final
investigation has shown that active over-voltage protection is
better solution than passive protection circuits with respect to
efficiency and reliability.

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.
