The Filière Energie et Techniques environnementales (FET) has the digital systems course and labs in the 3rd (autumn) semester. The semester counts 15 weeks and ends with a little project.
The aim to the project is to synchronise an AC motor used as a generator to a reference 50 HZ signal.
Specification
Function
The reference signal and the generator output are digitised to 1 bit with the help of two comparators. The digital circuit receives these signals and controls a DC motor coupled to the generator.
Circuit
Components
The system consists of
- an assembly of a DC motor and an AC generator
- an FPGA prototyping board
- a synchro I/O board with 2 sinewave inputs and a PWM output
Motor generator assembly
FPGA board
The main board is the school's FPGA-EBS lab development board. It hosts a Xilinx Spartan xc3s500e FPGA and features many different interfaces.
