What's the difference btw linear and switching power supply?

Postby sean » Sat Jan 10, 2015 6:07 pm

There are two main designs for the Volteq DC power supplies: Linear Power Supply, see this http://www.volteq.com/linear-dc-power-supply.htmland Switching Power Supply, see this: http://www.volteq.com/switching-power-supply.html.

The traditional linear power supplies are typically heavy, durable, and have low noise across low and high frequencies. For this reason they are mostly suitable for lower power applications where the weight does not pose a problem.

The switching power supplies are much lighter, more efficient, durable, and have limited high frequency noise due to the design. For this reason, the switching power supplies are not suitable for high frequency audio applications but are great for high power applications. Other than that, these two types are pretty much swappable for various applications, and they cost about the same to make.

We have seen some online seller saying that the switching power supplies are not suitable for plating or ionization, it is misleading and not true. In fact, all the Volteq switching power supplies come with over-voltage protection, and are better suited for applications with reverse EMF, like plating, anodizing, DC motors, RC cars, electrolysis, battery charging, etc.
