I am trying to design an AC/DC power supply for an LED aquarium light. My plan is to create a switching power supply which will first rectify the AC to a DC voltage before using switching to step the voltage down using a higher frequency transformer.

At the moment my concern is should my power supply be designed to handle surges in the mains line due to lightning strikes? In all three of the books listed above no attention is given to this topic. I know that it is important to address inrush current to the capacitor, but I do not think any of these techniques would prevent current in the event of a lightning strike.

Based on the lack of information in these books and some information from other stack exchange threads Creating an isolated power supply to prevent effects of lightning I am under the impression that surges from lightning strikes is just something these electronics are not designed for. The main goal of this post is to first confirm that my impression is correct. Secondly I wanted to see if there are any best practices to handle surges from lightning strikes for indoor AC to DC power supplies.

You're really asking the wrong question. If you're thinking about selling something that plugs into the wall in any volume, step back and figure out what the applicable UL standards are. There will certainly be some kind of surge test along the lines of IEC61000:4-5. There will be creepage, clearance, and isolation requirements. There will probably be a maximum acceptable temperature rise as well. If after figuring this out you still want to create a product, you would be smart to hire a consultant to review the design before going to UL for testing. This may cost a few grand, but failure will be even more expensive.

This fully revised, comprehensive guide to switching power supply and design contains new information relevant to solar power applications

Switching Power Supply Design and Optimization, Second Edition covers the design and optimization of electronic power supplies that incorporates switching regulators to effect the efficient conversion of electrical power. The book has been updated and expanded to include discussions of the latest advances in the field as well as increased breadth and depth of topics previously covered.

New to this Edition:
