“…In contrast to the circuit‐level modelling, which considers only the ideal model of power switches, the device‐level real‐time simulation of power converters is becoming popular in recent years. It is capable to present the detailed IGBT/diode transient voltage and current waveforms [5]. Therefore, the switching power dissipations can be computed, which further contributes to the electro‐thermal converter model [6].…”

Power electronic converters are essential components in the fuel cell electric vehicle (FCEV) powertrain, which precisely control the power output of the fuel cell stack, the charging and discharging process of the battery, and the operation of the traction motor. The hardware-in-the-loop (HIL) simulation plays an important role in the rapid validation of power converters in their early development stages. In this study, a device-level model of the power converters in FCEV powertrain is developed for the FPGA-based real-time simulation. By fulfilling the circuit topology partitioning and the switch model partitioning, the FCEV power electronic system can be simulated with sub-microsecond time-step while producing the detailed switching waveforms with 5 ns resolution. Therefore, the device electrical stress, and the switching power losses can be evaluated in real time. Furthermore, the electro-thermal converter model is developed accordingly, which makes it possible to evaluate the IGBT/ Diode thermal behaviour in the HIL simulation. In this study, the FPGA hardware is designed with the NI LABVIEW FPGA module and implemented on the NI-7975R FLEXRIO FPGA board. The accuracy of the FPGA-based simulation results is evaluated by the results from offline simulation tools. The effectiveness of the proposed model is then validated by the controller HIL experiments.

Cost efficient and timely power converter circuit design requires the minimization of the number of breadboard iterations. This can be accomplished through the use of computer-aided analysis tools that are capable of predicting the circuit performance accurately. New, physics based models for the circuit components, in particular semiconductor devices and magnetic elements, are being utilized. This paper presents a comprehensive analysis method that incorporates these models as well as models for board layout parasitics. A 250kHz forward converter circuit is simulated and circuit waveforms compared to breadboard measurements show a high level of accuracy. Sensitivity and worst case analysis can be performed using simulation results.
