6 FAQs about [Isolated Photovoltaic Inverter Application]

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 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 photovoltaic inverter?

One of the key components of the photovoltaic (PV) system is inverters due to their function as being an operative interface between PV and the utility grid or residential application. In addition, they can be employed as power quality conditioners at the point of common coupling (PCC).

Can cyclo-converter based inverter be used for PV module applications?

In , a novel single-stage isolated pulse-width-modulated (PWM) half-bridge cyclo-converter based MI for PV application is developed. A 250 W experimental prototype is constructed and the laboratory prototype has a peak efficiency of 94%. In , single-stage flyback inverter for ac PV module applications is proposed.

What is galvanic isolation in a microinverter?

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.

Are VSI-based inverter topologies suitable for PV microinverter applications?

Nevertheless, the VSI-based topologies can demonstrate equally high efficiencies of 96% and have been industrialized already in the PV microinverter applications. Regardless of the basic inverter topology, full-bridge solutions are the most popular due to their high control and modulation flexibility.
