Networked control technology
Modular control solutions for power electronics
Our proprietary networked control technology is at the heart of our fully programmable control systems.
This brings very high flexibility to our digital controllers, enabling them to control all sorts of power converters, ranging from conventional inverters to more complex modular, or multilevel power converters.
High-speed serial interconnect
Ultra-low latency communication protocol
Getting the most from the network topology
The imperix RealSync protocol exploits the particular characteristics of the networked control traffic in order to reduce latency. Notably, for the relatively small payloads involved, it turns out that tree-shaped network topologies offer a superior usage of the total available bandwidth.
|Data traffic (3000 nodes)||1-tree||2-tree||Gain|
|DTOT with 64 Bytes||557 µs||357 µs||x 1.5|
|DTOT with 16 Bytes||554 µs||119 µs||x 4.7|
The table shows the total data transfer delay DTOT for different values of payload size, as a function of the networked control topology. It appears that a pyramidal structure offers almost 5x superior performance versus the conventional ring-type networks.
Networked control implementation
Getting the most from distributed control
Our modular control systems rely heavily on FPGA devices for communication, signal processing and distributed modulation. That said, numerous distributed control strategies also require FPGAs.
In this context, imperix offers to its customers to edit both the CPU software – supporting automated code generation – as well as FPGA firmware. Development engineers can therefore also disseminate their own algorithms among the control network.
Imperix controllers support a broad range of programming frameworks
Engineers can add custom-designed FPGA firmware to all imperix controllers. To this end, the most common development environments and tools are supported, including Xilinx Vivado HLS, Xilinx System Generator, Matlab HDL Coder, and of course manual VHDL code edition.
Fully-Integrated development workflow
Our digital controllers benefit from the same control technology, software development environments, and performance characteristics. Therefore, they can me mixed inside the same control network, or can be substituted to each other as a function of the technical requirements.
From the computer to the laboratory
First, engineers can switch swiftly from computer-based simulation to prototype implementation, thanks to automated code generation tools.
From the laboratory to the field
Then, the usual re-start that occurs when moving from prototyping equipment to series hardware can be alleviated by directly using B-Board PRO for final products.
From prototypes to mature products
Finally, imperix customers always benefit from an always up-to-date equipment, which guarantees operation over the long run, independently of the hardware evolution.
