Re: 556 sstc idea---the circuit for the new Dual Mosfet

Hi All. I'm pretty late on the reply here, sorry.

I saw the circuit at http://www.nuenergy-dot-org/plasmatron.htm in a 1997
issue of Electronics Now magazine. I built the circuit several months
ago, but replaced the SG3526 with a 555 (because I had those ; ) and
a small N-channel MOSFET to invert. I left the push-pull stuff alone.

I noticed no shoot-through condition. None at all. Even using a
single oscillator and one transistor to invert....

Needless to say, my circuit was a little unstable (555) but still
performed okay.

I wouldn't use the 555 for this. I would stick with one of the
rock-solid PWM controller IC's. Like, for instance, the SG3526 ; )

Take care,
