FAQS 4
What are isolated microinverters?
Recently developed isolated microinverters were mainly based on center-tapped single or interleaved flyback converters in single-stage topology and DC–DC converters cascaded with half or full-bridge inverters in multi-stage topology. These converters are proposed to either increase the lifetime and efficiency or decrease the cost of components.
What is a solar PV inverter?
Early solar PV inverters were simply modules that dumped power onto the utility grid. Newer designs emphasize safety, intelligent grid integration, and cost reduction. Designers are looking to new technology, not used in existing solar inverter modules, to improve performance and reduce cost.
Why is galvanic isolation important in grid-connected photovoltaic microinverters?
Galvanic isolation in grid-connected photovoltaic (PV) microinverters is a very important feature concerning power quality and safety issues. However, high-frequency transformers and high switching losses degrade the efficiency of the isolated types of microinverters.
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.
