Issues related to power quality are a good arena for research.

Dear Barnabas Amakali,

I would like to propose a "Component Load Factor * " analysis of candidate 3 phase ac to isolated dc power converters with unidirectional power flow. This would be a simplified “figure of merit” type of comparison, largely for relative cost, and secondarily for potential efficiency.

Such converters are not suitable where bidirectional power flow is required, such as general purpose solid state transformers for a smart power grid, but have applications in, for example, high rate chargers for electric vehicles, variable speed wind turbines, and server farm power.

A common such converter uses a 3 phase boost pre-regulator followed by an isolated dc to dc converter stage, and other circuit options exist. My intuition is that a “dark horse” candidate may prove superior to other options: three single phase power factor correcting (PFC) flyback converters with the outputs connected in parallel.

A PFC flyback consists of a bridge rectifier input to a flyback converter, controlled to draw an input current proportional to the (rectified ac) input voltage. This single stage converter can use a single, ground referenced input power transistor, a single output high frequency rectifier, and a single power magnetic element.

Flyback converters are generally considered to be of “low performance”, suitable only for lower power levels. However, in a 1987 paper [15] I showed that forward and flyback converters were, when suitably compared, nearly identical in component utilization. The exception was in the magnetics; the flyback integrated the transformer and filter inductor of the forward converter into the transformer alone, merely by gapping the core, with savings in size, mass, cost and power loss.

Thus there is nothing intrinsically “low performance” about the flyback converter. Quite the contrary, it should be suitable for high power levels as well as low. I demonstrated this in two proof-of-concept 4.5 kW, 50 kHz PFC flyback converters (see attached seminar notes for a full description).

Efficiency was 96% over a wide load range with a 240 Vac input. A potential efficiency of 98% might be achieved at 480 Vac input (lower relative bridge rectifier losses) and the use of an energy recovery voltage clamp instead of a dissipative clamp with 1.1% loss at full load.

Additional advantages would be the elimination of the need of a large dc energy reservoir capacitor, and the ability to connect the single phase inputs in series for higher input voltages.

I will be available for some assistance, advice and guidance if you choose to accept this proposal.

Kind Regards,

Bruce Carsten

* A “Component Load Factor”, or CLF, is the dimensionless ratio of a power component type’s total volt-amp product per watt output, as described in [20]. Suitable voltage and current measures (peak, average, rms) are multiplied for each component of a type, the products summed and divided by the output power. The CLF gives a first measure of the cost of the component type, and also the power loss; the higher the CLF, the more the components will cost, and the higher the losses. A CLF can be calculated for power transistors, rectifiers (separately for low and high frequency types), magnetics (transformers and inductors), and filter and energy storage capacitors.

If you are looking in power domain then you should target integration of renewable energies in smart grid. I have recently graduated and I have done my final year project on demand side management by integrating renewable with the help of fuzzy controller. A simple microgrid you can design in MATLAB Simulink and Start your research career easily.

Dear Barnabas Amakali ;

I suggest :

Electric vehicles is an upcoming field.

On power systems, maybe something on optimising renewables for low load factor applications such as railway traction (where power in the 5MVA+ range is required in large peaks at times, with none at other times)

I also recommend electrical vehicles impacts on power systems with different % of current/power from the electric charger to the EV.

Barnabas Amakali, given your recent follow up question on focusing on the "electrical part of "waste-to-energy"", I would support Abdelghani Rouini 's recommendation of exploring energy storage systems. I think a very interesting work for you to draw inspiration from could be that of Vo et al. (2018). It gives a great overview and assessment of the use and benefit of energy storage through waste-to-energy technologies (in this case, anaerobic digestion) to deal with the limited electrical interconnectivity of Ireland. This kind of case study could be implemented for many different scenarios, waste-to-energy technologies, energy systems and/or locations, and could hopefully be of interests to you. You can find the paper here:
