| | Converter |
| | Abstract | My project was to see how different IGBT (Insulated Gate Bipolar |
| | Transistor) models affected the performance of a Cuk converter as |
| | simulated by PSpice. I expected the simulations with the simple model to |
| | run faster than the simulations with the Infineon model. I simulated 3 IGBT |
| | models: a mathematical model available from Infineon and 2 behavioral |
| | models. The first behavioral model was as simple as possible, a switch |
| | and voltage source. I added a resistor and capacitor in parallel to the |
| | device to create the second model (to simulate switching losses). To |
| | measure the usefulness of the simplified models, I ran simulations of the |
| | converter with each IGBT model but with one parameter changed to see |
| | how the converter responded to this change. I calculated high-level |
| | waveforms (such as efficiency, input power, and charging current) by |
| | integrating the functions over a 8.333ms period with PSpice and |
| | converting the integrals to normal averages and RMS averages with |
| | established formulae. I simulated the circuit over 108.333ms to generate |
| | steady state conditions rather than startup conditions. The high-level |
| | waveforms produced by the models were all within a few percent, |
| | proving that simpler models could simulate as well as a complicated one. In |
| | addition, the simplified models ran about 50 times faster than the Infineon |
| | model. The contributions made by this project are applicable in any IGBT |
| | use, especially the field of hybrid vehicles. |
