Vdc are the same of Vrms before FETs make their work! Thank you Andy for pointing out it!!

The PA is an half bridge like Andy's 700W but now I'm testing at low voltage: I se; /rsgb_lf_group-archives/html/rsgb_lf_group/2017-06/msg00010.html (27,871 bytes)

(score: 1): Author: Chris Wilson <[email protected]>; Date: Fri, 2 Jun 2017 14:14:18 +0100; Hello Marco, My loading coil drifts as it warms up, but that's only when a kW or so is run, not at low power. But I think you are testing into a dummy load? I also had a poor drain waveform on one si; /rsgb_lf_group-archives/html/rsgb_lf_group/2017-06/msg00011.html (10,337 bytes)
