MICROINVERSOR CON CAPACIDAD PARA MANEJAR UNA LÁMPARA DE LEDs
Resumen
Resumen
El presente artículo propone una novedosa topología que consiste en la integración de un microinversor con un driver de lámpara LEDs. El convertidor tiene la capacidad de funcionar como microinversor durante el día, inyectando toda la energía proveniente del panel fotovoltaico. Durante la noche el convertidor cambia de modo de operación y actúa como rectificador con alto factor de potencia para alimentar a una lámpara LEDs.
Ambos convertidores (microinversor y Driver) están basados en un convertidor Flyback que operan en modo de conducción discontinua (MCD).
Se muestra un análisis detallado del funcionamiento de la topología, las ecuaciones para el diseño de la misma y finalmente se presentan resultados de simulación.

MICROINVERTER WITH CAPACITY TO HANDLE A LED LAMP
Abstract
The present paper proposes a new topology integrating PV panel microinverter system and street lighting driver for a LED luminaire.
The converter has the capacity for working as microinverter during daylight injecting the energy provided of PV panel to the grid. Meanwhile at night the converter changes its operation, then it acts as rectifier with high power factor to provide energy for the LED luminaire. The topology present two integrated converters. These converters are based in Flyback converter opering in discontinuous-current mode (DCM).
The paper shows a detailed review of the topology function as well the equations used to design the topology and finally it shows the simulations results.
Keywords: Flyback Inverter, LED Driver, Microinverter, Street lighting.
