Hi All, To follow up. I raised the medium sphere to 7.25 inches from the top edge of the toroid to the center of the medum sphere. I then ran the coil at 300 Vfire where breakout was 100% of teh time and got the following: http://hot-streamer.com/temp/OLTC10-12-11.gif http://hot-streamer.com/temp/OLTC10-12-11.CSV 300 Vfire raised medium shpere (base current) PK FREQ kHz (Error +/-) Q FACTOR (Error +/-) LEVEL 1 36.693 (0.01%,4Hz) 38.48 (13.28%, 5.1) -0.1dB 2 115.250 (0.01%,13Hz) 26.23 (37.56%, 9.9) -21.6dB 3 176.060 (0.01%,20Hz) 32.00 (22.33%, 7.1) -24.3dB 4 109.558 (0.01%,13Hz) 76.51 (63.17%,48.3) -26.4dB 5 225.888 (0.01%,26Hz) 39.60 (13.28%, 5.3) -26.6dB 6 178.144 (0.01%,20Hz) 26.29 (22.33%, 5.9) -23.6dB Accounted for 95.16% of input signal I then found the point were breakout was about 50% of the time (Vfire = 270 VDC): http://hot-streamer.com/temp/OLTC10-12-12.gif http://hot-streamer.com/temp/OLTC10-12-12.CSV At about 50% breakout (base current) PK FREQ kHz (Error +/-) Q FACTOR (Error +/-) LEVEL 1 36.954 (0.01%,2Hz) 79.52 (6.64%, 5.3) -0.0dB 2 114.237 (0.01%,7Hz) 27.95 (31.58%, 8.8) -25.3dB 3 226.181 (0.01%,15Hz) 40.36 (18.78%, 7.6) -30.3dB 4 118.217 (0.01%,8Hz) 7.09 (22.33%, 1.6) -22.2dB 5 275.312 (0.01%,18Hz) 42.71 (26.56%,11.3) -33.0dB 6 182.147 (0.01%,12Hz) 15.37 (26.56%, 4.1) -27.7dB Accounted for 98.05% of input signal Cheers, Terry
