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.
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.
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.
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.
Galvanic isolation exists between the grid and the PV modules in isolated microinverter types. The presence of a high-frequency transformer in the microinverter topology usually provides this isolation. The PV voltage level's boost up and conversion into an AC voltage can be accomplished either by a single-stage or multi-stage conversion circuit.
