My expertise is in DC-DC, DC-AC converters to interface renewable energy sources to standalone power sinks, eg. electrical machines(rotating and linear), high frequency heating. I use Microchip microcontrollers and dsps for embedded control. At hardware level I am experienced in pcb layout and thermal management analysis.
From my long research and academic cum industrial experience and keeping abreast with the ever changing technology, I provide expertise in *Developing conceptual schemes in the field of Power Electronics, *Drives and Control *Hardware Design *PCB Design *Thermal Management. The high speed drives and high frequency switching are becoming more common and my research theme of increasing the switching frequency to reduce the physical sizes of inductances and bulk capacitors has now come into play. Currently developing sensored bldc motor drive pcb layout to be housed within a volume of 62 mm diameter and 70 mm height. Challenge is heat dissipation management and choosing the dc link capacitor to fit within.
I have interaction with 2 research projects, namely, (1) development of control system for 5 phase Permanent Magnet Synchronous Machine to operate in the extended field weakening range and (2) investigation of Protection System, for Low Frequency High Voltage Transmission using cycloconverter as frequency changer at the offshore platform. These activities keep me abreast of software tools and conceptual thinking.
Lectured in Power Electronics and Advanced Electronics Motor Drives. Supervised undergraduate final year projects.
Management in retail trade
My research activities were in soft switching of power electronics devices with an aim of reducing physical sizes of inductors and transformers. On the application side the research activities were in Electrical Drives. Supervised research students and co-authored 15 papers. As consultant to Davis Derby, I was responsible for 4 member team for conceptual and hardware design, prototyping and testing an autonomous battery charger for electric cars using specified 400 Hz switching frequency. The conceptual design comprised 3 main blocks, namely, two part 400Hz conical transformer, input rectifier-inverter including charge control and the third block was frequency modulated infra-red link between curb station and onboard battery system. I was leader of the power group. I was the programme manager for Higher National Diploma in Electrical & Electronic Engineering in the Department and 4 off campus franchises. I was programme manager for the Tempus Scheme.
