Photovoltaic inverter io board function

Using a Piccolo-A device integrated on the board lessens the burden of the controller used to control the solar power conditioning circuit control of the PV panel. Thus, the board uses two C2000 controllers, a dedicated Piccolo-A device is present on the baseboard and used to control the PV emulator stage.

C2000 microcontroller. A 250-W isolated micro inverter design presents all the necessary PV inverter functions using the Piccolo-B (F28035) control card. This document describes the power stages on the micro inverter board, as well as an incremental build level system that builds the software by verifying open loop operation and closed loop .

Function of the grid direct inverter. Synchronization with the grid is one of the key functions of a grid direct inverter. The inverter needs to generate a sinusoidal AC waveform at a fixed level from the PV panels, which has varying voltages depending on the sun’s irradiance, weather conditions and other factors.

The inverter is the heart of every PV plant; it converts direct current of the PV modules into grid-compliant alternating current and feeds this into the public grid. At the same time, it controls and monitors the entire plant.

This paper provides a systematic classification and detailed introduction of various intelligent optimization methods in a PV inverter system based on the traditional structure and typical control. The future trends and research topics are given to provide a reference for the intelligent optimization control in the PV system.
