Repairing Switching Mode Power Supplies

In this article Scott Dorsey tells us how to repair Switching Mode power supplies. As he explains, "there are a lot of books and articles out there about how to design a switching supply, but not many on fixing them. As switching supplies become ubiquitous in electronic devices today, it becomes that much more important to understand how they work and just as importantly how they fail." This article was originally published in audioXpress, January 2018.
