Modular structure of the AC 800PEC control system

The modular structure of the system means that it can be adapted to any size of application,

from the largest industrial equipment and propulsion systems to compact products where space and cost

are critical.

All over the world, thousands of processors have proved their worth in a wide range of extremely

demanding applications.

Powerful hardware for efficient high-speed processing

The AC 800PEC combines the floating-point performance of a CPU with the flexibility and high-speed

capability of an FPGA.

The system is divided into three performance levels covering different cycle times.

Control tasks are assigned depending on their speed requirements:

– Very fast tasks, down to 25 nanoseconds (nanoseconds for FPGA tasks)

– Fast tasks down to 100 μs (microseconds for Matlab/Simulink tasks)

– Slow tasks down to 1 ms (milliseconds for control tasks)

The hardware architecture of the AC 800PEC is complemented by a three-level software architecture.

To support short processing cycles, the AC 800PEC offers a fast I/O system.

Depending on the speed of the I/O connections, data throughput times can be less than 100 μs,

 including the time required to read, process, write and transmit signals.

Implementing the AC 800PEC software at three performance levels provides excellent control and

communication capabilities.

The following software packages have been developed to support each specific high power rectifier

application.
