Nigel Goodwin said:Well, yet again he's not got his location filled in, but 300A at 30V is 9000W, three times what you can get from a normal single phase socket in the UK.

carmusic said:does active rectifier with mosfet exist in single chip replacing classic bridge diode, i would need approx 50A capacity at 30V?
Somehow I don't think you'll be able to find anything with a forward voltage of less than 250mV at 300A, a huge Schottky rectifier maybe?sammyb11 said:I am looking for a single phase rectifier with a blocking voltage of at least 30V, current rating of 300A or greater, and a forward voltage of .25V or less. Does anyone know where I could find something like this or if they even exist?

If you are looking at older tech there was a mercury rectifier which could handle very very large currents, they were used to rectify power for trams.
