HYLEK – Highly Dynamic Power Amplifier for Emulating Electrical Components
As part of the HYLEK collaborative project, TU Ilmenau Transfer GmbH is working with ISLE GmbH to develop a highly dynamic power amplifier system for real-time emulation of electrical components. The goal is to create a test platform that allows power converters, drives, grid interfaces, and active loads to be tested under reproducible laboratory conditions without having to physically build the respective electrical environment from scratch.
The technical focus is on instantaneous control of complex current waveforms, short latency times, and flexible modulation methods. The system is designed to combine high pulse and modulation frequencies, precise current control, and scalable power electronics within a unified system architecture. In doing so, HYLEK specifically addresses applications in the areas of power hardware-in-the-loop, motor emulation, grid emulation, and system-level validation of power electronic devices.
TU Ilmenau Transfer GmbH is responsible for coordinating the project and developing the software and control-related system components. This includes defining the technical requirements, designing the digital control and communication architecture, implementing PWM, control, measurement, and diagnostic functions, and integrating the software modules into the overall system. Another focus is on evaluating system behavior in the closed-loop test bench, including interface testing, safety functions, and assessment of emulation quality.
HYLEK lays the foundation for a modular testing and emulation platform designed to make industrial development processes in power electronics more efficient, reproducible, and safer. The results are expected to be translated into new services, methods, and system solutions for the validation of modern power converter technologies.
