| Abstract |
Power hardware-in-the-loop (PHIL) emulation of batteries and electric machines is an efficient method to accelerate the development and testing process of traction inverters and their control systems at different operating conditions. This paper presents the overall setup of a high-bandwidth, high-voltage PHIL system. Real-time machine and battery models, a control unit for the power electronics device and the power electronic device itself are highlighted as the most relevant parts of the PHIL system. Multiple approaches fulfilling the requirements of these parts are explained in detail. Finally, this paper determines the most suitable approaches to setting up a modular PHIL system that is scalable in terms of power range and number of output connectors.The overall hardware of the PHIL system with the described components is set up. Concludingmeasurement results prove its performance. |
