The two I mentioned are the two best. You want
Advances in Switched-Mode Power Conversion, volumes 1 and 2, R. D. Middlebrook and Slobodan Cuk, TESLAco 1983, or else the two papers,
Design Techniques for Preventing Input-Filter Oscillations in Switched-Mode Regulators, by R. D. Middlebrook, from the Proceedings of Powercon 5, the Fifth National Solid-State power Conversion Conference, May 4 - 6 1978, San Francisco, CA, and
Modelling and Design of the Cuk Converter, R. D. Middlebrook, from the Proceedings of Powercon 6, the Sixth National Solid-State power Conversion Conference, May 2 - 4 1979, Miami FL. I'm not sure you can get the two papers anywhere else. Dr. Middlebrook is a genius electronics scientist, and Dr. Cuk is a gifted electronics scientist and a genius inventor. IMHO, the advances these people have made in the science of switched-mode power conversion, and in fact in power conversion in general, stand head and shoulders above anyone else in the field. They are generally ignored for several political reasons, and deserve any promotion they can get.
For general reference, if you decide to continue with your boost converter instead, try
Switching Power Supply Design, by Abraham I. Pressman, McGraw-Hill, 1998 (Second Edition). The ISBN for SPSD is 0-07-052236-7; I don't think ASMPC has an ISBN number.
If you insist upon owning ASMPC, as I did, you can get it from TESLAco at 213/795-1699. If that number doesn't work, let me know, or google up TESLAco. You'll find Dr. Middlebrook's canonical model far more useful in modeling your converter than anything Pressman has to tell you; but Pressman has considerably more material on many other SMPS designs, and it is considerably better organized, not to mention being something a little more coherent and accessible than a large collection of scholarly technical papers, which is all that Middlebrook and Cuk have to offer.
On edit: I hope it's "helping you no end," rather than "helping you
to no end." I'm sure it is.
