Primera Comunicación con el Cosmos en Latinoamérica -PERU-RUSSIA

TVUNI — 26 de agosto de 2009 — El Jueves 20 de Agosto se llevó a cabo el 1er radioenlace en Latinoamérica con el Cosmos. Esta comunicación se llevó a cabo en la Universidad Nacional de Ingeniería del Perú a las 13:32, hora local, y lo cual marcó un hito en la historia de las telecomunicaciones del Perú y Latinoamérica. El radioenlace tuvo una duración de 10 minutos en los cuales el rector de la UNI Mag. Ing. Aurelio Padilla Ríos se comunicó con el comandante ruso de la EEI Gennady Ivanovich Padalka quien tuvo frases de elogio y gratos recuerdos del Perú. TV UNI © 2009. Lima, Perú.

Chinese Physics C



Chinese Physics C covers research into the theory, experiment and applications of particle physics, nuclear physics and astrophysics.

Announcement from IOP Publishing

From January 2009, Chinese Physics C (formerly High Energy Physics and Nuclear Physics) will be hosted and distributed (outside mainland China) by IOP Publishing.

Chinese Physics C (formerly High Energy Physics and Nuclear Physics) was founded in 1977. It is sponsored by the Chinese Physical Society and supported by the Institute of High Energy Physics and the Institute of Modern Physics of the Chinese Academy of Sciences.

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.
