The IO337 I/O module is an ideal fit for demanding power electronics testing applications, such as
- Controller HIL testing of inverters, converters (e.g. MMCs), and motor drives.
- Testing at ultra-high switching frequencies
- Testing motor drives at rated power levels (Power HIL)
The IO337, based on an AMD® Zynq™ UltraScale+™ MPSoC with 653k logic cells, allows to emulate several motor drives on a single I/O module.
The IO337’s FPGA is equipped with 32 ultra-highspeed, low-latency analog channels enabling DAC outputs at 10 Msps and therefore allowing closed loop control rates / simulation step sizes of >1 MHz.
The IO337 can be programmed directly from Simulink with automatic HDL code generation, using the HDL Coder™ workflow from MathWorks®. Highly dynamic models and I/O run directly onto the FPGA in deterministic real-time. The HDL Coder™ workflow also supports Simscape™ and Simscape™ Electrical™ models. All Power Electronics HIL test models featuring common topologies provided by Speedgoat have been tested and run seamlessly on the IO337 making it a turnkey solution.
