Research Projects

Fault Detection and Protection for Solar PV Systems

Discover unique fault scenarios in solar PV arrays and develop new fault detection and protection methods.

Photovoltaic Inverter/charger Combo Microgrid

Campers, soldiers and outdoor enthusiasts now have access to portable, foldable, flexible solar arrays. We are designing new charging algorithms that use these new solar technologies to recharge NiMH and Li-ion batteries.

Project on High-Temp. DC-DC converter

Funded by Army Research Laboratories, we are developing high power density (2" by 2") 100W DC-DC converters that can withstand ambient operating temperatures of up to 125C.

Project on Digital Sliding Mode Pulsed Current Averaging IC drivers for High-Brightness LEDs

Northeastern University is working jointly with Exclara Inc. of San Jose, CA to design and implement Sliding Mode Pulsed Current Averaging IC drivers for the application of High-Brightness Light Emitting Diodes. The phase- I project was funded by US Department of Energy.

High Power Density DC-DC Converters for Telecommunication Power Supplies

Using integrated magnetics, multi-layer (10) pcb, and newly invented DC-DC converter topologies, we have introduced and are marketing new approaches to achieve 48V to 3.3V/2.5V/1.8V/1.5V conversion. We have achieved faster response and higher power efficiency, while utilizing standard brick and 1/16 brick package sizes.

Integrated Magnetic 1/4 brick Dc-Dc converter

When announced (in 2002) this quarter brick telecom converter was among the first to achieve power density greater than 100 W/cubic inch.
