Validation of eHS FPGA reconfigurable low-latency electric and power electronic circuit solver

This paper discusses the validation process and example of power electronic circuits simulated with a general purpose solver implemented on FPGA chips. The `Electric Hardware Solver´ or eHS presented in this paper has the goal to facilitate the usage of FPGA for high-fidelity Hardware-In-the-Loop simulation with sub-microsecond time step by avoiding the difficulties associated with the coding of FPGA devices. Several examples, from very simple to more complex using one or several FPGA boards, are presented and results are compared with traditional simulation software such as SimPowerSystems and PLECS. It will be demonstrated that FPGA-based simulation is now accessible to control and simulation system specialists without requiring any FPGA programming skills. In fact, preparation of FPGA simulation requires only the use of PLECS or SimPowerSystems schematic user interface.
