Hardware-in-the-loop testing of high switching frequency power electronics converters

Abstract

In this paper, we present the Hardware-In-The-Loop (HIL) usage of a new simulation approach recently introduced by the authors and discuss the programmable logic interface required for the HIL simulation of high switching frequency power electronics converters. As a test case, we simulate a notional ship power system where one converter is externally controlled using the developed HIL simulation platform. The ship system is composed of eight converters all operating at 100kHz, the real-time simulation is performed using a FPGA-based platform and a 50 nanosecond simulation time step.
