B-Box RCP 3.0
Rapid prototyping controller
The B-Box RCP accelerates the development
and experimental validation of converter control
techniques in a laboratory environment.
B-Box RCP is a modular control platform, exclusively tailored
for Rapid Control Prototyping (RCP) 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 notably distinguishes from other RCP solutions
by its fully programmable analog front-end, its advanced
Pulse-Width Modulation (PWM) capabilities, as well as its
numerous and specialized I/Os.
Also, this system has been designed from the start with syn-
chronous sampling applications in mind. It therefore offers
a large configurability and guarantees a very strict man-
agement of timings and phase shifts, from analog inputs
to PWM outputs, including in networked configurations.
Performance is not left on the side either, since its dual-core
ARM processor and Kintex-grade FPGA support closed loop
control application up to hundreds of kHz ! Besides, for the
most demanding applications, B-Boxes can be stacked up
forming a networked control system of up to 64 units and
thousands of I/Os.
Networked B-Box configurations are supported by RealSync,
a proprietary technology that guarantees sub-μs transfer
latency and ns-scale synchronization accuracy. Thanks to
this technology, stacked configurations can be used in a
totally transparent fashion, as if all FPGA resources and I/Os
belonged to one single controller.
Thanks to its high flexibility, practically any power electronic
application can be ideally addressed with B-Box RCP, rang-
ing from grid-tied appliances to electric drives, energy stor-
age systems, renewables, electric mobility, etc.
That said, B-Box RCP is most attractive in demanding appli-
cations, either in terms of I/O count (e.g. multilevel convert-
ers), in terms of performance or even both. Notably, systems
based on wide band gap devices such as SiC or GaN often
simultaneously require high-precision PWM generation as
well as a fast closed-loop control speed.
