This may be horribly simplistic, but as these are 12V Halogens, would a
possible approach simply be to rectify the current, so instead of
125kHz AC, it becomes DC? Or have I missed the point somewhere?
You'd have to rectify *and* smooth *and* maintain the same RMS voltage
into the load.
If you just rectify, you dont have to smooth, and the RMS voltage into
the load will be the same..although there is still an HF component..of
reduced amplitude.
I still think Andy should amaze us by calculating the correct capacitor
to put on the end to make it a zero reactive load..
Lets see. 2 ohms at 125 KHZ..
I make that 0.6uF.
So sticking a 0,6uF capacitor across the far end of the cable should
make it all soring to brightness again.
