A 50 kW Power Hardware-in-the-Loop Test Bench for Permanent Magnet Synchronous Machines based on a Modular Multilevel Converter

This paper presents a power hardware-in-the-loop (PHIL) test bench for the emulation of highly utilized permanent magnet synchronous machines based on a square-wave powered Modular Multilevel Converter (SPMMC). Comparisons of the measurement results between an automotive machine and the PHIL during steady state operation and high dynamic current steps are done to show the performance of the PHIL test bench.
