Stuck on capacitance

[davelectronic]

Interesting ideas, i thought dimmers where not usable for inductive loads. Not the resistive types anyway. if i could have changed the wave form in the primarys (with out over heating the windings) I would have used a dimmer on the single primary winding. I have finished the pair of transformers in series, both primary and secondarys. I'm getting 20.70 Volts AC with no load, and 17.60 Volts with 200 watts of halogen lamp load, 4 x 50 watt lamps. The cable i used is advertised as being capable of currents up to 30 Amps at 12.00 Volts. I don't know it could handle that much current, but at 200 watts, i'm almost certain it can handle a bit more current. i'd say 18 Amps to 20 Amps with a 50% duty cycle wouldn't be unreasonable, although i'd expect to drop a bit more voltage form the secondary input due to the lower series primary input. But its looking good so far. I didn't do the stat's for a 200 x 100 x 20 mm piece of aluminium plate as a heatsink for 4 x TIP36C transistors. And the rectifier, i wasn't happy with the aluminium it was bolted to with the transformer chassis assembly. Hopefully with air flow it will keep things cool.

Thank you for all the help with this issue, hopefully I've accomplished a usable power source in the two MOT transformers. Just sharing a tip or two, I found silicone PTFE spray really helped max out the windings count. Also made a purpose tool (old screwdriver) rounded off and polished the tip (now bull nose for want of a better discription) pushed in the other side allowing the cable to follow this tool until I could pull it through, and creating more turns count. Another quick tip on checking voltage per turns count, a dress makers pin pushed through the insulation to check the voltage. The tiny hole closes up when the pin is withdrawn. You could just take a reading on voltage from the end your winding, but I felt volts drop over a length of unwound cable might not give an accurate result.
Thanks again for the help.
