10-500 MHz inductive heating
10-500 MHz inductive heating
(OP)
I am materials person wanting to heat ferrite powders in the low MHz range. A US patent 5208443 (http://freepatentsonline.com/5208443.pdf, column 11 of text) has some equipment description for making a small coil (for <40MHz) that would work (although the freq range is limited). The description appears to be just connect a power supply to a transmatch to a coil - is it that simple? It seems that there should be a signal source as well? Any advice about parts to make this kind of system or a broadband version would be greatly appreciated. Of course low power and/or shielding will be needed...





RE: 10-500 MHz inductive heating
The common frequencies for induction heating are in the range of line frequency to several MHz, but I never came across an installation operating at more than 10 MHz.
You always need some king of matching ciruit, in the lower frequency range switched capacitors, for the higher frequencies a matchbox consiting of variable capacitors or inductors.
I will check the patent later and provide additional hints if necessary.
