Hi Johan, yes a quick look suggests a value of anything over about 120uH would do the job at 136 with a 10ohm load. I looked for data when I started to experiment as I am sure you did and just built
Hi Alan, I never could get a handle on using passive components to feed pulse amps , a sort of contradiction ? what do they do in a mobile phone ? G .. Hi Joe , Thanks for the "plug" :-)) Yes the cir
Johan and LF, During my experiments with class E the choke was not a component to which I paid great attention. Having said that, when operating at 500khz, I tried reducing the value to around a few
Hi Graham I think it is a misunderstanding to think that the power supply must supply peaks of current. This is what the choke avoids, there will be some ripple on the supply but it should be quite m
Hi Graham, well there is not a lot of difference between "pulse amps" and any other sort really from that point of view. The choke "opposes changes in current" and also allows the signal to go to the
Ok Alan, Ok , no problem on the 'isolation' using a inductor , I was thinking more of the power supply demand/regulation side of things , looks like these things are a bit tricky to feed 'dc' interms
Alan, Johan and group, Since experimenting on LF I have discovered the joys of Class E, many thanks to Alan. My first 100W TX used an IRF-640 as suggested on Alan's web page. A dozen of them could be
Hi Joe , Thanks for the "plug" :-)) Yes the circulating currents get pretty large with the low impednces when you try to put high power out with 12 supply. It doesnt do some caps a lot of good either
