Hi, first of all I will declare a commercial interest here as my company supplies just such a system. Components are a power supply, function generator, heating coil and control electronics, sample enclosure, sample insulation etc to avoid non specific heating and temperature sensor - I've attached a few references for your information. If you require any further details please do not hesitate to contact me directly - [email protected]

Yeah, thanks so much, Carl :) That is precious information for me. I'll contact you directly after discussion with my advisor. ^_^

Hi Carl, thanks for the info. We have a system for induction heating for magnetic hyperthermia in our lab (not from NanoTherics) but our problem is that we are not being able to push the current higher than a certain value. My generator is 10 kw, but maximum power transfer is only 2.5 kw. We are unable to pump higher current. Our coils are made of copper and they are water cooled.

Any help is well appreciated.

Hi,

Power transfer depends on quite a few factors, capacitors, losses, core saturation etc without specifics its difficult to say.

Why do you need a higher power transfer than 2.5 kW anyway as this should generate fields far above medically acceptable limits ?

Regards

Hi Carl,

            This is in continuation to our earlier discussion. I am getting a field of 0.82 kA/m only at 2.5 kW power transfer. I have copper coils (water cooled), diameter is 50 cm and six turn. The current increases if we put a solid metal inside the coil. Otherwise for magnetic nanofluids we are not being able to push the current. Will be waiting for your response as we find the problem very fascinating. Will also be happy to provide further details if required. Nevertheless, I am not an electrical/electronics engineer. So pardon my limited technical knowhow.  Thanks.
