FAQs about Photovoltaic panel isolation circuit
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.
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.
What are the different types of isolators used in solar power conversion?
In a solar power conversion system, different types of isolators are adopted to serve various functions. Isolated gate drivers are used to drive insulated gate bipolar transistors (IGBTs) or metal-oxide semiconductor field-effect transistors (MOSFETs) in the high-voltage power stage.
How to reduce OVC in solar power conversion?
For solar power conversion systems with galvanic isolation between the grid-tied circuits and PV circuits (Figure 3), the impulse voltage rating of the grid-tied circuits and PV circuits are determined in the previous two bullets. The isolation transformer between the PV circuits and grid-tied circuits can reduce the OVC.
