Can't figure out why this circuit causes "cannot find solution"
Circuit layout -
Ac in (240rms 60hz)
Full bridge then npn/zinger 6v
555 timer 50% 60kHz
Feeding a sink/source bridge driving
Isolation transformer
The problem didn't start until i added the bridge
If i recreate the circuit with just a 5vdc source and a 5vdc pulsing source it works fine. She here

Been staring at it for hours and can't find the problem. Any help is appreciated.
