Can any one suggest good thesis topics for Power Electronics??

Hi ,

I am a Masters student with specialization in power electronics, Can any one suggest good thesis topics in Power Electronics or on topics such as BUCK/BOOST/flyback/forward Converters...etc

thanks

How about a 3 phase constant power ( or torque) variable speed synchronous AC motor drive?  Interesting
challenge when HexFets first came out, probably two chips and a pot now, though.

Interface to allow a local power source (solar, wind) to feed back to the grid?  There are commercial gadgets
to do this, but smaller/better/cheaper is always good.  Sure would be nice to have one for my exercise bike
so I could at least feel like I am doing some useful work.

I also recently saw a device to allow Police to essentially hot tap into the mains with a UPS to allow them to
confiscate a running computer without shutting it down.  Surely must be some interesting power/switching
electronics going on there.

Regulated charger for electric vehicles that measures total draw for the house then maximizes the charge
rate staying under the house service max, i.e. ~200 amps for the car when nothing else is running but
drops down when the AC kicks on or the electric stove is turned on.  If this hasn't been invented, this is my
disclosure and I have dibs (US, anyway).

Obviously all of these should be monitored or controlled by LabView, maybe even LV embedded with a PDA
interface.

Matt,

You can have the NLED, but I get credit for the DED (Dark Emitting Diode) (usually pronounced "dead"). This is what is left after you have removed all the light from LEDs (especially if done rapidly by using very large currents).

Thanks for your reply Matt..Can u suggest me some topics on Converter's...I was interested in converters but cant think of a good topic

Hi Sandeep.  I think all of those gadgets except for the motor speed controller will require a converter of
one sort or another, and you could probably make a case for having one in the speed controller anyway.

Another area might be a device to 0 phase a reactive load.  I think the EU has been big on forcing devices
to be natively resistive but it could be fun to make a 'universal re-phaser' that would make any load look
resistive to the mains.  Obviously you can brute force it with AC->DC->AC, but I wonder if there is a way
to do it with only one conversion, or adjustment, step.

I may have also completely missed the point of what you are trying to do 😉

Lynn:

We sometimes used NLEDs to create DEDs, although we never managed to reverse the process.  The DED devices
did seem to have an amazing level of reliability, though, especially for such small production lot devices, even over the
full mil-spec temperature range.  They just keep on working!
