Outdoor Power Supply Electrical Topology

Are power supply topologies still used today?

For most power supply applications, a handful of topologies continue to be used after more than 30 years. Simplicity and ruggedness keep these circuits relevant today. At the beginning of modern power supply design, about thirty years ago, there were a handful of topologies that served the industry well.

What is a power supply topology?

Let's first clarify what is a power supply topology. Switch mode power supply (SMPS) circuits contain networks of energy storage inductors and capacitors as well as power handling transistors and rectifiers. Their particular configuration is what's referred to as a topology. Here I will help you select the right one for your application.

How to choose the right switching power supply topology?

The right switching power supply topology for a given application should be selected based on specific requirements for the power supply design including cost, size, time factors, and expected production volume. For example, for low-volume designs, the engineering expenses may be more important than BOM cost.

When did power supply design start?

At the beginning of modern power supply design, about thirty years ago, there were a handful of topologies that served the industry well. In the 1980s, an explosion of research into new and advanced power conversion techniques created hundreds of new topologies that could be used.

How to design a power supply?

Key Components in Power Supply Design Step up or step down AC voltage before rectification. Isolate input and output for safety. Convert AC to DC using diodes or bridge rectifiers. Half-wave or full-wave configurations affect efficiency and ripple. Smooth out rectified DC by reducing ripple voltage.
