Mini DRSSTC first light

This mini TC has 15cm long secondary, and producing about 20cm long sparks
half bridge consist of two IGBTs - HGTG11N120CND.
Preformance is nothing extra but this is not full power cause i have some chokes on mains, in future i wanna run this mini coil with full bridge or put a doubler on bridge as those IGBTs are dimensioned for 1200V.

Hi nice drsstc, do you used OCD for protect yours IGBTs? and used variac transformer for increased the voltage or how many volts and amps used in your half bridge?

[plasmatron6]

@80927269 no, this has a simple driver with no protection, and bridge supply is about 200V and limmitaded current with some chokes

I can't help thinking this coil sounds

more like a interupted SSTC and

not a DRSSTC as it lacks the 'throated'

crackle sound of a tuned primary....if that makes any sense?...lol

[plasmatron6]

that cause i set a quite low PW on interrupter, maybe..

Whats your secondary frequency?

[plasmatron6]

324 kHz with toroid, what do you thing will these igbts survive at 650V?

Hi, nice work DRSSTC, what driver used for this , can you send me the schematic please.

[80927269]

Hi Can you send me the schematic of you interrupter please?

[Tab54o]

Guess that depends on your primary current. Lower your pulse width to like 50uS or less once you ramp voltage to 650. You'll probably have to destroy one set to see how they perform at that voltage and frequency +pulse width. There is surely a point at which they will survive but what output you get at that setting is anyone's guess.

holy macaroni, look at the 1:50 part with that stick which was probably cursed somwhere, but that doesnt matter , those light bolts just remind me .....of the good old times .............. just love that part, and where could i download the intro song??
