An FPGA-based Real-Time Digital Simulator for Power Electronic Systems

-Testing digital controllers for power electronic systems in real-time using a real-time digital simulator presents a problem, due to the discrete nature of the controller outputs which are not necessarily in synchronism with the time-step of the simulator. Reducing the simulation time-step resolves the issues resulting from the lack of synchronism between the digital simulator and the hardware...

UMEC Transformer Model for the Real Time Digital Simulator

This paper introduces the UMEC (Unified Magnetic Equivalent Circuit) transformer model recently implemented for the RTDS Simulator. The UMEC transformer algorithm was reorganized to meet the requirement of real time simulation. The detailed implementation and optimization of the algorithm are described. Validation of the model is also presented. The validation was conducted by comparing the rea...
