Multi-Core Processing for Complex Models
The RT Box 2 speeds up the simulation of complex models of power electronics circuits. Models that can be split into separate physical sub-systems will benefit from the parallel processing capability. The RT Box 2 also offers additional analog and digital interfaces plus a solid-state drive for data storage.
If you are looking for a real-time simulator with more analog and digital I/Os, you might want to consider the RT Box 3.
Processor
The RT Box 2 employs the latest generation Xilinx Zynq Ultrascale+ multiprocessor system-on-chip. Of its four Cortex-A53 CPU cores, up to three can be used for real-time simulation calculations, while the remaining core runs an embedded Linux for communication and ancillary services. The FPGA inside the Zynq Ultrascale+ is currently used to control the analog data converters and the the digital I/Os. With future releases of the PLECS Coder and the RT Box firmware, the user will be able to compute parts of the simulation model with time-steps in the sub-microsecond range on the FPGA.
Analog I/O
Compared to the RT Box 1, the maximum sample rate of the analog I/Os has been increased to 5 Msps and the settling time of the analog outputs has been halved to 0.5 µs.
Resolver I/O
When used for HIL simulation, the RT Box 2 can emulate a magnetic resolver with an analog bandwidth of up to 10 MHz. The RT Box 2 also features a resolver-to-digital converter for position evaluation in control application.
