Power converter controllers

Specialized control solutions

Fully-programmable digital controllers for power electronic applications

Imperix offers a complete family of power converter controllers, supporting the whole life cycle of power conversion systems, from R&D to commercial products.

Thanks to their high flexibility of their software and hardware, they facilitate the experimental validation of control techniques for all sorts of power electronic converters.

Key features and characteristics

Our controllers help engineers to design, test, and validate digital control techniques for power conversion systems. They enable them to save time during both development and product prototyping phases, thanks to their high level of specialization.

Typical applications include electric motor drives, grid-tied inverters (e.g. solar inverters), energy storage systems (e.g. battery) or multilevel converters. There are practically no boundaries to what can be implemented.

1 – System programming

The controllers can be easily programmed using C/C++ code or using automated code generation toolboxes for Simulink and PLECS.

All it takes to flash a converter control software (user code) on the controllers is one click. Code generation, compilation and upload on the devices are fully automated. Besides, no particular skills are needed.

2 – Run-time execution

The controllers can be used alongside a computer or as standalone devices. In both cases, direct insight into the code execution is guaranteed the BB Control Utility software.

This way, B-Box RCP can be used as a desktop-based development platform, while B-Board PRO is rather meant to be an integrated controller within a larger system.

3 – Live monitoring

The BB Control Utility enables users to access, monitor and tune any variable in real-time, supporting the close supervision of the power converter’s operation and control dynamics.

The utility also provides a datalogging capabilities similar to an oscilloscope. This allows logging every data point, thereby facilitating the tuning of control parameters.


Power converter controller for laboratory prototyping applications

The B-Box RCP is a highly flexible power converter control system, tailored for rapid control prototyping applications in power electronics. Thanks to its high performance and flexibility, it facilitates the experimental validation of power converters control techniques in R&D environments.

The B-Box RCP is entirely and exclusively tailored to be a rapid prototyping controller. It notably distinghuishes by the very high flexibility of its analog front-end and specialized I/O interfaces.

Also, B-Box RCP has been designed for synchronous sampling applications and a strict management of timings, from analog inputs to PWM outputs, including in stacked configurations.

B-Box RCP embeds the latest processing devices, including a dual-core ARM processor and Kintex-grade FPGA.

Together with an ultra-light and specialized operating system, this guarantees state-of-the-art performance for all closed-loop control applications. Running a converter control algorithm in the hundreds of kHz range becomes no longer a challenge!

Multiple B-Box units can be stacked together to build up larger controllers. Up to 64 boxes can be combined, extending up to thousands of I/Os!

This brings high flexibility in time and accross multiple projects. It is always possible to combine (or separate) units depending on the varying needs of their applications.

The B-Box RCP is built over a strong hardware abstraction layer, which guarantees the stability of its operation – as a platform – over time and accross the evolution of its own hardware.

This way, it is guaranteed that a code that works today will still work in the future , even though the hardware will most certainly have changed in-between.

B-Board PRO

Power converter controller for product-embedded applications

The B-Board PRO is the heart of the B-Box RCP controller. It is also available as a standalone controller for embedded applications. The board feature a ZynQ-based dual-core ARM processor and a Kintex-grade FPGA (Xilinx Zynq), plus advanced communication capabilities and extensive I/Os.

The B-Board PRO can be programmed using either C/C++ or directly from simulation software, such as Simulink or PLECS. Thanks to a fully automated code generation toolchain, just one single click is all it needs to fully program the device!

With Simulink, the provided blocksets also embed simulation models so that the system behavior can be accurately simulated and tuned before run-time. Then, everything truly works from the first test!

Absolutely no expertise in FPGA-based development is needed to work with the B-Board, as it operates readily with a highly flexible and highly configurable FPGA firmware.

Nevertheless, for the most advanced users who require to alter the FPGA code, the B-Board allows to do so. In this case, dedicated areas are provided, with straightforward integration within the existing DSP software kernel.

The B-Board PRO uses a dual-core processor. One core is dedicated to the execution of the closed-loop control tasks (bare metal, dedicated kernel), the other one to the system supervision and monitoring (linux). Most low-level tasks are also shifted in FPGA.

This results in the full dedication of a fast floating-point processor core to real time control tasks, with best-in-class performance, ranging up to 200kHz control frequencies in closed-loop operation.


In addition to being 100% compatible with B-Box, the B-Board PRO benefits from the same software environment and tools. It can be programmed from Simulink and controlled from BB Control too!

Overall, most of the specific integration efforts are only those related to the mechanical aspects as well as the signal conditioning and protection, which are often tailored to the application anyway.


What if you could simply take the result of your research and put it into an affordable controller, directly embeded inside your own products?

Software solutions

The Automated Code Generation (ACG) SDK enables engineers to program the B-Box RCP and B-Board PRO controllers directly from Simulink or PLECS. The provided toolchain handles fully automated code generation, compilation and upload in just one click.

In addition, the SDK contains simulation models of each controller peripheral, so that the exact system behavior can be simulated – and hence easily anticipated – before code is generated.

Power modules

Imperix power modules are ready-to-use building blocks allowing to build up almost any converter topology. They exist in various power ratings and internal structures. Each module features:

  • Power semiconductors
  • Gate drivers
  • Voltage and current sensors (with local protection)
