How It Works: The Current Doubler Demystified

Focus:

The current doubler is a particularly useful rectifier configuration for low-voltage or high-current outputs. However, some engineers may be confused as to how the current doubler works. Fortunately, there are similarities between the current doubler and the dual-phase buck converter. In this article, an analogy with the dual-phase buck converter is used to explain how the current doubler operates. Prior to the explanation, the author discusses the advantages and disadvantages of the current doubler versus other circuit architectures. Article ends by discussing the use of synchronous rectification in current doublers.

What you’ll learn:

• How to understand the operation of the current doubler
