Effective Thermal Management for Inverters
Inverters are key building parts in energy conversion. Thermal power losses in inverters occur during operation due to electrical resistance and switching losses in the semiconductor chips. The losses result from the conversion of direct and alternating current AC/DC. It is crucial to minimize these losses by transferring them to the heat sink in the best possible way to increase the overall efficiency.
Inverters
Inverters are built either from discrete components or with power modules. Typically, IGBTs and MOSFETs are used, and increasingly advanced SiC and GaN chips. The latter offer higher switching speeds and better power efficiency. However, they generate more heat, so even more efficient thermal management is required.
thermal conductive materials
For optimized heat flow, various thermal conductive materials can be used. These include thermal conductive pastes (TCP), phase change materials (PCM), ultra thermally conductive silicone-carbon films without dielectric insulation properties and thermally conductive insulating films such as thermosilicone films or PCM coated Kapton and polyimide films as well as thermally conductive silicone caps and sleeves with insulation properties. When designing-in electrical insulation films, attention must be paid to creepage distances and CTI in addition to thermal conductivity and insulation requirements.
