This paper further examines the use of mixed-signal circuits for power system emulation. It has already been proven that analog emulation overcomes the speed limits of numerical simulators by means of a simple fixed-topology prototype. In order to enhance the modularity and the size of the emulated power system a dedicated platform based on a field programmable power network system (FPPNS) has been developed. This platform contains an application specific integrated circuit as main building block. Details on the designed hardware are given in this paper. Furthermore the emulator is validated comparing its emulation results with numerical reference simulations. The promising results of this platform show that the design of a fully integrated solution containing an array of 100 atoms can be started.
