Inverters

1. Overview

Optoelectronics inverters are power electronic devices that convert direct current (DC) to alternating current (AC), integrating optical sensing and control technologies. They play a critical role in renewable energy systems, industrial automation, and grid-connected applications by enabling efficient energy conversion and system monitoring through optoelectronic components such as photodiodes and optocouplers.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Grid-Tied Inverters	Synchronizes with utility grid, no battery storage	Residential solar PV systems
Off-Grid Inverters	Operates independently from utility grid	Remote power systems
Hybrid Inverters	Combines grid-tied and battery storage functions	Smart energy storage systems
Microinverters	Panel-level DC-AC conversion with MPPT	Building-integrated photovoltaics

3. Structure and Components

Typical architecture includes:

Power stage: IGBT/MOSFET modules for DC-AC conversion
Optical sensors: For voltage/current isolation monitoring
