Hello

You may want to try the other Yahoo group, "switchmode", they may have the answers you're looking for.


Good luck,

Hi,
i was thinking that the main component what i have used is of LT and so this group should be aiding me.

Thanks

Yoga,

You are missing a ground on the bottom half of your circuit. Here are some other comments:
1. You could 'clean up' your circuit by combining all the parallel caps and series resistors.
2. You don't need any caps in parallel with the DC voltage sources that have zero resistance.
3. Your current pulses aren't going to work right, because the sum of the various times exceeds the period.
