Preamble

In remote area, the use PV is great potential to power the eletrical devices. The need for the inverters to interface with PV, energy storage and appliances are growing in the other countries, where the grid is not strong enough to cover the area.

Objective

The objective is to design a multi-port inverter, which can integrate the PV, energy storage and appliances.

Partial Specifications

The inverter should have at least three ports:
1) A 250W DC port for PV output
2) A 1000W bidirectional DC port for battery storage @ 48V
3) A 120V, 1000W AC port for appliances.
A control system will enable the battery charging when the PV has output and supply the appliances through the battery.

Suggested Approach

The team should investigate the literature of the multi-port inverter and study the control system for the inverter. The suggested approach is as following:
1) Design the power topology of multi-port inverter.
2) Design a control system to enable the function of each port
3) Create a simulation model to validate the design
4) Build a prototype to test the functions.

Group Responsibilities

The group should response for designing the inverter, test and validate the functions of the inverter

Student A Responsibilities

Student A will design the inverter power topologies.

Student B Responsibilities

Student B will design the hardware of inverter with control system

Student C Responsibilities

Student C will create the simulation model for inverter with controller

Student D Responsibilities

Student D will program the controller and test the functions.
