In an isolated converter, the input and output stage have separate grounds whereas in a non-isolated converter, current is able to flow directly between the two sides as they share a common ground. Isolation is usually created by incorporating a transformer in the circuit so that power is transferred using electromagnetic energy.
In short, an isolated power converter isolates the input from the output by electrically and physically separating the circuit into two sections preventing direct current flow between input and output, typically achieved by using a transformer.
A non-isolated power converter has a single circuit in which current can flow between the input and output. For those not familiar with power supplies this leads to additional questions: What are the benefits of isolated vs non-isolated power supplies? And how do I know which one I need for my application?
In contrast, isolated converters alleviate safety concerns since the input and output sides are separated by a transformer, ensuring different grounds for the primary and secondary sides.
Isolated DC/DC converters, such as flyback, forward, half & full-bridge, and LLC, are prevalent. These converters utilize a transformer to separate the input (primary side) and output (secondary side). The turn ratio of the transformer allows these converters to operate without constraints on the input-to-output voltage.
The isolated type of DC:DC converter, the category to which Alencon's SPOT and BOSS devices belong, can be particularly advantageous over the non-isolated type for a number of reasons, including: 1. They isolate the grounding between input and output – meaning the grounding scheme of the DC source can be different from the load on the output 2.
