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.
Is basic isolation sufficient in a solar power conversion system?
Basic isolation is suficient if another basic isolation is inserted through the isolated data links. In the solar power conversion system (Figure 2), the digital isolator needs to support reinforced isolation because the isolated gate drivers and amplifiers are referenced to DC–, and only functional isolations are implemented.
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.
Do solar inverters and energy storage systems have a power conversion system?
Today this is state of the art that these systems have a power conversion system (PCS) for battery storage integrated. This application note outlines the most relevant power topology considerations for designing power stages commonly used in Solar Inverters and Energy Storage Systems (ESS). Figure 2-1.
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?
What is a result of isolation in a non-isolated converter?
A result of isolation is that each of the isolated circuits has its own return or ground reference. In a non-isolated converter, as shown on the left side of Figure 1, the input and output share a common ground and current can flow between them.
