Re: Low Hy? How about no Hy?

Ray,

I think the concept has merit, but can be improved on. A large capacitance at the I/P of a PSU filter introduces ripple freq. overtones into the B+ rail. A choke seems better to me for killing that sort of crud than a regulator is. However, if the I/P capacitance is kept reasonably small, the ripple fundamental will be dominant and the regulator WILL kill it. Set things up along the lines used with vacuum rectification. Place the bulk of the energy storage at the end of the filter.
