Hi Trauts22.
First I'm appalled at some of the comments from the experts, I respect their opinion and knowledge though.
Nobody corrected you about the frequency. Induction heaters for hobs use 50-100 KHz and not MHz, they should have picked that up when you described the coil.
My name and Trauts22's name end with 22 it's because we both belong to a secret religion that believe in unicorns.How do you correct fairy tale devices, it's like debating unicorns. I've seen some overunity knobs claim GHz frequencies.
Hi Tony.here are some DIY plasma lamp power supplies, but do use a microwave like light/ RF shield.
I should warn you, RF power in hundred watts with hundred MHz range is Caterogenic, meaning, causes bloodshot eyes then cataracts after prolong use.
Even a Tx into a dummy load without a lid to the lossy coils will cause bloodshot eyes after a day. ( just ask Jack Askew on web).... hehe Although I haven't seen him for 35 yrs he used to get this at work.
Hi Tony.
Interesting information.
If the induction hob is used do you know of similar danger? The frequency of the hob is likely to be 35KHz and not more than 100KHz.
The original idea try to prove that you can get better efficiency. It's based on comparing measurement of power only, they ignore the fact that light output and efficiency of halogen lamps isn't linear with power or temperature of the filament. If you power a bulb with higher voltage the efficiency rises but the life decreases.
