Development of a smart LED lighting system: Rapid prototyping scenario

The goal of this work is the development of a LED driver system for industrial and domestic use, which integrates an AC-DC PFC interleaved boost converter, a resonant DC-DC LLC high efficiency converter, a low-level LED control and a fault detection component. Efficient energy use and harmonics reduction are the main goals to be achieved. AC-DC power stage has been designed to operate in interleaved mode and several control techniques have been tested to increase performances; a linear control has been implemented for the resonant converter; low-level LED control includes a fault detection capabilities. The approaches of simulation and rapid prototyping have been deeply exploited in this work to make faster design and test phases for each individual functional block and to minimize errors. The behaviour of the LED control component has been also compared with a real prototype.
