I've made a custom flyback+driver with which to power my coil gun. I have two 15v, 6.3amp laptop power supplies. I want to use both of them in parallel to power the flyback so I can draw more current. I am currently using 1 of them. Is there anything special I should do to connect these in parallel? Should I put diodes in series with each power supply to prevent current backwash into each PSU?

diodes on the + and gnd should work to effectively isolate them from each other. search "paralleling psu's" on here, I believe there was a discussion about it for powering a subwoofer.

Thanks I'll search for that topic. Quick question though, - should I put diodes on the + and ground of Each PSU, or the + and ground of only 1 of them.
