Hi, I found another old 240V transformer in my shed and would like to make a 36-39V DC power supply, the transformer outputs 39V AC unloaded, when I connected a 1000V 50A full wave rectifier bridge to the DC output it drops a bit to about 37V DC. However when I connected a 63V, 6800 uF capacitor to the bridges' DC output the DC voltage jumped up to 55.4V DC unloaded.
So my questions are:
How does the capacitance value figure into it and do I match the capacitor V to the voltage I want or is there something simple that I need to do.
Thanks.
