Global semiconductor company Infineon Technologies (Korea CEO Seung-soo Lee) has enabled more accurate system-level simulation in various applications where switching power and thermal performance are critical, such as EV charging, solar power, motor drives, energy storage systems (ESS), and industrial power supplies, through an update to its power simulation platform.

Infineon announced on the 27th that it has newly added SPICE-based model creation capabilities to its power simulation platform IPOSIM (Infineon Power Simulation Platform).

IPOSIM has already been widely used to calculate the losses and thermal behavior of power modules, discrete devices, and disk devices.

The newly added SPICE-based model generation tool calculates static, dynamic, and thermal performance more precisely by considering nonlinear semiconductor physical characteristics.

It enables comparison of device performance under various operating conditions and provides realistic simulations by reflecting the actual selection of gate drivers.

In addition, key parameters such as parasitic inductance, gate voltage, and dead time were reflected.

This allows developers to customize the application environment, reduce design iterations, and shorten time-to-market.

GloA full-scale transition to carbon neutrality requires the implementation of clean energy systems, sustainable transportation, and efficient industrial processes.

Accordingly, designers are facing the challenge of reducing development costs while providing high-efficiency and high-power density designs for EV chargers, solar inverters, motor drives, and the like.

While conventional hardware testing is time-consuming and costly and struggles to fully reflect real-world conditions, IPOSIM’s SPICE integration is garnering attention as an alternative capable of overcoming these limitations.

The new SPICE-based model is fully integrated into IPOSIM's multi-device comparison workflow.

Users can select a device displaying the SPICE icon, configure the application environment, and then proceed with the simulation by following the instructions.

It provides an intuitive workflow, enables rapid device selection, and supports highly reliable design decisions. Furthermore, designers can perform system simulations reflecting actual conditions from the early stages of development, allowing for simultaneous application performance optimization and cost reduction.
