Help with plasma controller build

The bridge rectifier values should be higher than your output. 50A 600V is a common value, for example. You need aluminium electrolytic capacitor. One or more wired in parallel to the DC output of the rectifier. The voltage should exceed your output values, 80V or the more common 100V. Regarding the capacitance, the larger the better, but they are not cheap. I recommend at least 20.000 uF. You may find these large capacitors also with screw terminals that are easier to wire, without the need of soldering. On the toroid mains input I would put a simple glass fuse, T4A (time delay fuse). Not sure about the output fuse, probably a circuit breaker will be more robust. Personally I have only the fuse on the mains.
