5. Libraries of components and materials

GT-PowerForge comes built-in with a broad range of libraries of off-the-shelf references for all major components and materials of a converter’s power train.

These libraries are assembled from manufacturer-provided data using Gamma Technologies’ internal expertise, resulting in a harmonized, universal data set that enables comparison across manufacturers and technologies.

Users can also add their own private references, for exclusive use within their organization.

• 5.1. Power switches: discretes & modules
• 5.2. Packages
• 5.3. Capacitors
• 5.4. Magnetic materials
• 5.5. Electrical Machines
• 5.6. Frequency-domain limits

5.7. Metals

In power electronics, metals are used :

• as electrical conductors in the windings of magnetic components

• as thermal conductions in the baseplate and fins of heatsinks

The two usual metals commonly used for these purposes are available in GT-PowerForge.

Parameter	Aluminum	Copper
Density	2 700 kg/m³	8 960 kg/m³
Resistivity ρ20°C	28.2 e-9 Ω.m	17.2 e-9 Ω.m
Temperature coefficient α	0.0039 /°C	0.003862 /°C
Thermal conductivity	237 W/m/°C	390 W/m/°C
Relative permeability μr	1	1

The resistivity depends on the temperature T (in °C) as follows:ssss

\(ρ(T) = ρ_{20°C} \cdot (1 + α \cdot (T - 20))\)
