Platform provides automated lifetime estimation for selecting semiconductor components

18-03-2022 | Infineon | Design & Manufacture

Infineon Power Simulation platform (IPOSIM) from Infineon Technologies AG is widely employed for calculating losses and thermal behaviour of power modules, discretes and disc devices. The platform offers easy access to analysis for single working points and user-defined load profiles. For industrial customers, estimating the lifetime of power modules is becoming more importance in the early design stage of power electronics systems. This is particularly challenging for small and medium-sized companies as they lack the resources to set up and run suitable simulations. To support these companies, the platform now offers a new premium feature, an automated service that provides easy lifetime estimation of components according to usage and application needs.


IPOSIM Lifetime Estimation is an industry-first service that offers online access to the lifetime estimation algorithm and its unique expertise to simplify the design process. Customers can access the company's power electronics expertise online 24/7, as often as required throughout the design process.


The user-friendly GUI is created to guide designers in a step-by-step process through the simulation with power devices. A total of 19 topologies for discs and modules are offered, grouped by power conversion type. Also, the platform enables the multi-selection of up to five Infineon products for performance comparison. The finished designs may be saved and shared through deep-link.


With these features, it helps in selecting the suitable high-power products according to the application's needs. It can also decrease the time needed to set up and perform lifetime estimations and lessen overall development costs. Also, the service, with its highly reliable simulation results, optimises product sizing, reduces BOM, and offers faster time-to-market.


The service starts with one of the most commonly employed topologies in the power electronics design: a module-based three-phase two-level inverter. Other topologies will also be added soon. Users can choose the power module to be simulated with the configured modulation algorithm and load type. Specific mission profiles can be inserted through a CSV file or with displayed tables. Finally, the particular cooling conditions and gate resistance values will need to be added. The summary lifetime estimation parameters will need to be confirmed, and then the platform starts processing the data. The final report may be downloaded as a PDF file.
