RESUMEN
En este artículo se discute el diseño y operación de un convertidor forward con amarre activo con el uso de un transformador con derivación central, con el fin de aprovechar las ventajas de este convertidor en aplicaciones de bajos niveles de tensión y alta corrie nte de salida. Se explor ó el uso de un rectificador de onda completa del tipo síncrono en el secundario del transformador con derivación central para observar las mejoras que este puede ofrecer en cuanto eficiencia sobre valores de bajos de tensión. Se diseñó entonces un convertidor forward que tenga un rango de alimentación de +36 V a +75 V con una salida de voltaje de +5 V a una potencia de 150 W. Se presentan los resultados de simulación para niveles de entrada de +48 V, +36 V y +75 V.
Palabras Clave: amarre activo, forward, rectificador síncrono
ABSTRACT
In this paper the design and performance of an active clamp forward converter using a center t apped transformer is discussed to take the advantage of this converter topology in low voltage and high current applications. The usage of a synchronous full wave rectifier in the center tapped secondary of the transformer to show the efficiency improvemen ts in low output voltages levels was also explored. For this a synchronous forward converter was designed considering a range of +36 V to +75 V as power supply for a +5 V output voltage and a maximum output power of 150 watts. Results are shown in simulati on for +36 V, +48 V and +75 V input voltage.
Keywords: Active Clamp, Forward synchronous rectifier
