The ongoing transition towards electrified transportation results in the increasing utilization of resonant converters with relatively high switching frequencies. Hardware-in-the-Loop testing plays an important role in the design and validation process of novel converter topologies and controllers. This paper addresses the challenges related to achieving a high degree of simulation fidelity of resonant converters for a hybrid electric aircraft application. An FPGA-based real-time simulation with oversampling of switching signals and high-order numerical integration method is proposed. A high degree of simulation fidelity of the overall DC-DC converter system, a hybrid DC-DC converter consisting of CLLC and LLC converters, is achieved.
