SMPS: Symmetrical Isolated Converters

The previous article in our series on switched-mode power supplies (SMPS) covered asymmetrical isolated converter topologies. Now we will investigate several symmetrical isolated converters along with their advantages and disadvantages for different applications. Symmetrical converters require an even number of switches. The full available flux swing in both quadrants of the B-H loop is used, thus...

SMPS: Asymmetrical Isolated Converters

The previous article in our series on switched-mode power supplies (SMPS) covered non-isolated converter topologies. Now we will investigate isolated converters, starting with asymmetrical converter topologies. Isolated Converter Overview Isolated topologies in switched-mode power supplies use a high frequency transformer as an isolator between the switching element and output. Depending on the transformer turns ratio,...

Intro to Switched-Mode Power Supplies (SMPS)

Switched-mode power supplies (SMPS) are fairly complex compared to linear regulated power supplies. But this complexity results in a stable, regulated DC supply that can deliver power more efficiently for a given size, weight and cost.This article is the first in a series on switched-mode power supplies, their various topologies, benefits, and applications. Introduction: Power...
