Hi Jeffrey
I think the fault that blew the tants and rectifier was connection to another of the regulator circuits, either in phase or reverse connection, I am not sure which.
The circuit was assembled by someone else not me, and I agree a larger reservoir/smoothing cap would be beneficial.
So a 5 amp diode in circuit with each rectifier should protect the regulator, in the event of a high positive voltage being connected to the output.
Something like this;
But what about the case of a short circuit over current, how can the rectifier be protected.
What are efuses, they are discussed on the web but there does not seem to be anywhere that supplies them.
What one needs is a small self contained efuse IC which can trip accurately in the event of a fault and then be reset by removing the supply. Is there such a thing?
