Abstract
The power loss estimation is a crucial step for power electronics design, especially for high-power-density systems. Many mathematical approaches are known for power loss estimation, but the system design time can be lowered significantly if a simulation approach is used. This paper discusses the MATLAB-based simulation method for estimating power losses in the three-phase VSI. This simulation is using a real characteristic of the used IGBT transistors for power loss estimation. Next, the model uses the simulated power losses and calculates temperatures at different points in the simulated model. For the visualization, Fusion360 was used to simulate the thermal spreading at the heatsink. Finally, the inverter power losses are measured at the different loads to confirm the accuracy of the model. The temperature of the heatsink is measured with a thermal imaging camera and surface mounted probes.
