Past Projects

A Wireless Smart House Application (WSHA), Jan.2004 - Aug.2005
The WSHA is basically a wireless home network that utilizes the Zigbee wireless protocol to control HVAC and lighting loads in the household. Several nodes will be distributed in the household with each node controlling specific loads that are in close proximity to it. This project was funded by LSSU’s School of Engineering and Technology and IEEE Region 4.

A Low Voltage Regulator for Dual Voltage Automotive Electrical Systems, Jan.2003 – Jan.2004
Programmed the Infineon C505C-L microcontroller and built necessary hardware to implement a scheme where the 14V bus is provided by a 14V tap on a 42V battery instead of using a conventional DC/DC converter for providing the 14V bus.

AC Battery Heating for Cold Climates, Mar.2000 – Dec.2002
Developed methods to internally heat EV/HEV batteries at cold temperatures using high frequency AC currents. A high frequency 10-20 kHz inverter was designed for warming nickel metal hydride (NiMH) batteries. Additional tests need to be conducted to document the effect of high frequency AC currents on battery life. This project was conducted at University of Toledo's Power Electronics Laboratory (PEL) and funded by NREL.

A Selective Boost Equalizer for NiMH Batteries, Aug.1998 -  March 2000
Designed a relay matrix for charging weak EV/HEV batteries in a “round robin” manner. Programmed the Motorola M68376 microcontroller for sensing the voltage and temperature of each battery module, and controlling the switching of relays in the relay matrix. Designed and built necessary hardware and displayed data on a remote personal computer using Visual Basic. This project was conducted at PEL and funded by NREL.
