Hi
After making a sstc and getting good results i thought id have a go at making a DRSSTC using the same secondary as my sstc ( Frez is around 200 Khz )
So after making a small single 555 interupter and half bridge i finnay got arcs :D
Specs are
Secondary - 4" Wide x 5" High , Fres of around 200 Khz Driver is a PLL 4046 with primary feedback , only a 1:50 CT at the moment . Half Bridge of 35A 1.2Kv IGBT's Half Bridge Caps 1uF 1000v 15 Amp U Fast reverse recovery diodes 480v TVS Diodes Bi directional across C-E on IGBTs 18 Volt Zener Diodes on gates 10 Ohm Gate Resistors 1:1.5 GDT 10 T : 15 T Primary Capacitor is poloyprop 117.5 nF Primary Turns is 4
Supply 230v AC recitified .
I should put the filter caps at the bridge but ended up not doing it . I could get more out id say but tuning on a drsstc for me is still abit confusing and as my first DRSSTC im happy with the results , and no heating on IGBTs on lower breaks either , i do have a Oscope so i will scope primary current soon to see what it is . I have scoped the interrupter to make sure its working aswell
Spark lengh at lowest BPS i can get on my interrupter are 9.5 Inches .
