Abstract: The digital control of power electrical converters, such as thyristor converters for electrical drives or High Voltage D.C. transmission, is a hard problem. The quickness of the process, the complexity and diversity of the tasks and their interactions make the use of generally-used real time systems design impossible. Consequently, we have developed for this class of processes a conception method structured in three steps: choice of algorithms and formalization, research of a functional solution, implementation. This method appeals to the Interpreted Petri Nets (IPN) for the description of the tasks (first step) and the control (second step) of their activations. A dedicated multi-processor using fast bit sliced microprocessors has been developed to facilitate the implementation of this class of applications
