Hello, Here's a scenario: You have a 3 phase full wave power rectifier with one SCR open circuited (not firing). What is the effect on the load? Is it possible that this condition would cause abnormal heat buildup if the load was a battery being charged? I'm also trying to understand the current flow - current rating relationship of the components. For example, we are using 3500amp SCRs w/ 4000 amp fuses on a piece of equipment that will conduct 8000+ amps (electroplating). How would I determine what current rating is required based on total current draw? Thanks!
