| Abstract |
A high-fidelity real-time simulation environment is of substantial importance for reliable Hardware-In-the-Loop~(HIL) testing. This paper addresses the challenge of achieving a high degree of simulation fidelity for real-time simulation of high-power medium-voltage three-phase Dual-Active Bridge (DAB3) converters.Modulation schemes with high-resolution are applied for high-power DAB3 converters, even when a relatively low switching frequency is adopted. To achieve a high degree of simulation fidelity, gate signals provided by controller must be sampled within real-time simulation environment at a sufficient frequency. This paper proposes an analytical approach to determining the required sampling frequency for the gate signals in the case of DAB3 converters where we emphasize the importance of considering the operating range of phase-shift angle. Finally, a Field Programmable Gate Array (FPGA) based simulation environment that meets the requirements for high-fidelity real-time simulation of high-power DAB3 converters is presented. |
