A New Time-Based Converter Model Applied to Converter Automated Design

This paper presents an accurate virtual prototyping modeling technique for power converter using a time-based approach that overcome the simplification made in analytical models, and constitutes a better alternative for simulator-based models in the domain of validity. The key importance of the approach lies on its simple implementation and genericity, the electrical waveforms are obtained directly from the circuit equation and control sequences giving higher degree of freedom for the modeling process and making it less fastidious compared to analytical model. The model is intended for direct prototyping, hence, a precise wide-band-gap semiconductors model that include information about the thermal cycling is included. A case study for 3-Level multiplex inverter is conducted and experimentally validated with 15kW prototype.
