Real-time modeling of multi-level megawatt class power converters for Hardware-In-the-Loop testing

Hardware-In-the-Loop (HIL) testing using real-time simulation allows system designers to lower risks associated with system integration of new technology. Controller HIL (CHIL) is used here to verify the controller platform of a 15 MW amplifier that will be used as a grid simulator in Power HIL (PHIL) configuration. This allows elements of a smart electrical distribution system to be tested in an anticipated power system in a controlled laboratory environment. Details include a description of CHIL testing with simulation results and experimental results of the hardware implementation with open circuit measurements at the 24 kV experimental bus.
