Technical Highlights
Compact Design – Everything in a 19" rack, mobile and easy to integrate.
High Efficiency – Efficiencies of up to 99 %.
Wide Frequency Range – Sine frequencies up to 4 kHz, switching frequencies up to 50 kHz.
Powerful – Simulated active power of up to 558 kW per 8HE power module.
Intuitive operation of the active cooling unit – Touchscreen with clear status display
Technical Description
The IRS SiC Roadrunner is a compact Active Motor Load Emulator designed specifically for the requirements of modern inverters. With a maximum DC voltage of 950 V and a DC current of up to 600 A, the system enables the simulation of highly dynamic load profiles under realistic conditions. Thanks to a wide frequency spectrum – sine frequencies up to 4,000 Hz and switching frequencies up to 50 kHz – the Roadrunner is ideally suited for testing in the areas of electromobility, power electronics, and energy sector.
The simulated active power of the test specimen is an impressive 558 kW.
Despite this enormous testing performance, the system requires only a connection power of about 16–20 kW and is operated via a CEE three-phase power supply 400 V / 32 A (other variants, e.g. for US power grids, available upon request).
An integrated cooling unit ensures efficient heat dissipation and additionally provides forward and return connections for cooling the specimen.
This allows even extremely powerful tests to be conducted with minimal grid load and without external cooling infrastructure – a decisive advantage for laboratories with limited resources and maximum cost efficiency through low operating costs and the elimination of additional investments.
The emulator impresses with an efficiency of 98.74 %. Thus, almost all the energy used is utilized for the simulation while losses remain minimal.
The system is housed in a robust, mobile rack and offers compact plug systems for connecting high-voltage lines as well as standardized interfaces such as CAN and fiber optic communication (POF) for easy integration into existing test benches. The cooling circuits are easily accessible via forward and return connections. Operation is via an intuitive touch interface that allows for clear visualization of all operating states.
With its compact design, high performance, and flexible configuration options, the IRS SiC Roadrunner is the ideal solution for demanding inverter tests in the smallest space – and with a connection power that is insignificantly small compared to the simulated test performance.
