Automated generation of a FPGA-based oversampling model of power electronic circuits

Abstract

Power electronic devices are growing in importance in automotive applications. Power converters are used in hybrid electric vehicles but also in other vehicle applications like electric steering systems. For testing electronic equipment, hardware-in-the-loop simulation is a today's standard method in the automotive industry. It always requires a real-time simulation of the plant. For testing the electronic control units of power electronics, real-time capable models of power electronic circuits need to be developed, accordingly. This paper presents an approach for an automated generation of a FPGA-based oversampling model of power electronic circuits. Two types of modeling methods for considering the nonlinear switching behavior will be compared. For applying the oversampling approach a generator is presented, which automates a FPGA-based implementation of the circuit model. The approach is proven by simulation and measurement results.
