Re: Hash through chassis ground

Posted by Gary P on April 3, 2003 at 06:51:42:
One big advantage of the hybrid rectifier arrangement is there is very little or no reverse recovery spike to deal with.
To generate a reverse recovery spike it takes reverse current. The rectifier tube does not have reverse recovery issues hence no reverse current at switching. The 2 diodes are in series so if no reverse current flows back through the rectifier tube, there is no reverse current in the SS diode either. With no reverse current the switching hash becomes a non issue.
