The target of AmSy is to synchronize a synchronous machine with the grid either manually or automatically. AmSy should lead with its manual mode through the process and serve as a crutch to understand the synchronisation process. Furthermore, it should simulate the industrial use of a synchronisation such as a generator in a power plant with its automatical mode.

Out of all synchronisations methods we decided to use the principle of a light dark circuit because it is the cheapest and simplest method to synchronize a generator with the grid. We use a synchronous machine as a generator that will be connected to the grid. To drive this generator we use a direct current machine. Both of these machines need an excitation so we had to consider different way to excite those machines. Because adjustable transformers would have had needed a too high mechanical effort we decided to use a phase cutting control.

A microcontroller has been chosen to control the process because it is cheaper than a PLC. The microcontroller operates with 5 Volt DC. We had to design a board to convert the higher voltage of 400 Volt AC to a lower voltage level of 5 Volt AC and then to rectify the signal with an operational amplifier for the use with the microcontroller. We developed and constructed the housing suitable for all our components. To guarantee a preferable easy to operate device we designed the assembly of all in and output components very carefully.
