Impact of the Noise on the Emulated Grid Voltage Signal in Hardware-in-the-Loop Used in Power Converters

This work evaluates the impact of input voltage noise on a Hardware-In-the-Loop (HIL) system used in emulation power converters. A poor signal-to-noise ratio (SNR) can compromise accuracy and precision model, even make certain techniques for building mathematical models unfeasible. The case study presents effects digitally controlled totem-pole converter emulated with low-cost HIL using an FPGA. model outputs, cost influence different hardware implementations, are evaluated. signals may limit benefits increasing resolution model.
