| Abstract |
To emulate the reaction of an electrical machine interacting with a device-under-test inverter, apower-hardware-in-the-loop emulator has to provide a suitable countervoltage per phase. For the correct emulation of the dynamic electrical behavior of the machine, especially the current ripple, the countervoltage has to include a steady oscillating component and a stepwise changing component. This paper introduces a novel approach to determine the analytically ideal shape of the countervoltage for the emulation of three-phase machines and provides a simulative validation. As example, a synchronous machine operated with a two-level voltage source inverter is regarded. It is shown that the relation between the machine's direct and quadrature inductances as well as the coupling between the device-under-test inverter and the emulator have a significant influence on the shape of the countervoltage. |
