Update on the Kilowatt amp project - bench testing of voltage doubler

Here is a picture of the voltage doubler board under bench testing. For the test, the transformer primary is fed with a 11 volts AC source.

NEVER do a bench test like this with full High Voltage!!!!!

The transformer is rated 900 volts at 0.8 Ampere, with 230 volts on the primary. With 11 volts AC on the primary the calculated DC output after voltage doubling and filtering should be 133 volts. On the picture you can see the DVM reading 126.8 volts. Very close to the predicted value!

The total capacitance of the capacitor bank is 47uF and the voltage rating is 4000 KV. Under no load conditions, that will give a safety margin close to 50%. I'm contemplating reducing the number of capacitors to 8 in order to save som space. In that case, I would have a safety margin of 18% under no load conditions. I'd be happy to take comments on that!

I have also continued with the metal work of the cabinet. It is almost done, and I will update with pictures in the next few days.
