Hi everyone,
I'm intending to work on a DRSSTC soon! It's my second coil, my first was a SSTC based on Loneocean's SSTC 2 and Steve Ward's mini SSTC.
Here are the calculated specs for my planned DRSSTC: Secondary: 6cm dia, 18cm length, 1400 turns, AWG36, 296.45kHz Primary: 12cm dia, 3cm length, 6 turns, AWG14, 245.15kHz (17% detuned) Topload: 4.5cm minor dia, 18cm major dia Tank cap: 0.068uF 3kV CDE IGBTs: FGA60N65SMD, halfbridge Coupling: 0.187
1. I would be really happy to know how much I should detune my primary so that it can take advantage of streamer loading. Currently at 6 turns, the primary is detuned 17% lower than the secondary. Is that way too much? 2. Additionally, for a coil of this size and these IGBTs, how high should my OCD be at? I am thinking around 300A? 3. What would be a good coupling coefficient for this coil? Is 0.2 a better number?
