We propose the introduction of a new feature, "Dual Stage Electro-Thermal Simulation," in SIMBA. This feature is designed to accelerate the simulations aimed at calculating the thermal losses of power converters and junction temperature of semiconductors. The idea is to divide the simulation into two distincts consecutive phases:
Stage 1: Electrical Analysis
In the initial stage, the simulation runs exclusively in the control and electrical domains without considering thermal effects. This phase aims to accurately capture the steady-state current and voltage waveforms across all switches.
Stage 2: Thermal Analysis
The second stage leverages the waveforms obtained from Stage 1 and simulate only the thermal model. It estimates the switching and conduction losses in all switches. Since this stage deals with a reduced circuit complexity and can utilize a larger time step, it should significantly reduce the total simulation time.
