Isolated vs Non-Isolated Photovoltaic Inverters

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 converterhas a single circuit in which current can flow between. . Galvanic isolation (usually simplified to just isolation) is the physical and electrical separation between one section of a circuit and another. A result of isolation is that each of the isolated. . While there are many benefits to isolation, there are also reasons to use a non-isolated converter including cost, size, and performance. . There are several cases where an isolated power supply may be required or provide some benefit in an application. These include safety compliance,. [pdf]

FAQS about Isolated vs Non-Isolated Photovoltaic Inverters

What is the difference between isolated and non-isolated power supplies?

What's the Difference Between Isolated and Non-Isolated Power Supplies? 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.

What is the difference between isolated and non-isolated converters?

While isolated converters may not be as efficient or large as non-isolated converters, their isolation feature may be critical for use in medical, military and heavy industrial applications. Non-isolated converters are mostly used in Point of Load (POL) applications, where they convert from higher to lower voltages.

What is a non-isolated power converter?

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?

Why should I use an isolated power converter?

Safety requirements are a common reason to use an isolated power converter. For converters powered from high and potentially hazardous voltages (such as ac-dc converters powered from ac mains) isolation separates the output from dangerous voltages on the input. When safety is the concern, the insulation grade must also be considered.

What isolation options are available for solar power conversion applications?

In response to these needs, Texas Instruments offers several isolation offerings for solar power conversion applications. These include isolated IGBT gate drivers, digital isolators, isolated delta-sigma ADCs and amplifiers, and isolated communication links such as isolated RS-485 and isolated CAN.

Do solar power converters need isolation?

In a solar power converter, high-voltage and low-voltage circuits co-exist. Isolations are required between the high-voltage and low-voltage circuits for both functional and safety purposes. Fundamental isolation concepts and terminology are presented in references [3-4]. Digital isolators can be used to address the isolation requirements.
