This repository contains all necessary files for the "Grid Storage Interface". The primary goal is to design and size a DC/AC converter interfacing a battery storage system to a low voltage grid.
Project Overview The project involves the following key design parameters and outputs:
Design Parameters
- Application: Storage system interface
- Rated Power (AC side): 200 kW
- Low Voltage Grid: 400Vrms line-line ± 10% 50 Hz
- Storage System: Battery voltage range 700-800V
- DC/AC Converter: Two-level VSI
- Efficiency Target: ≥ 97% at full load
- Output Current THD: Max 3% at rated power
- Power Factor: Unity at AC side
- Cooling: Air cooled
- Overload Capacity: 110% of rated load for 60 s
- Ambient Temperature: 0-40°C
Design Outputs
- Preliminary sizing and component stress calculations
- Power switches selection and losses computation
- Thermal design and validation
- Capacitors and gate driver design
- Sensing components selection
