Abstract : In this paper a new class of converters power will be studied (Parallel Multicell Chopper). The topology of these chopper is based on a combination of n cells switching interconnected via independent inductors. This type of choppers is a new DC/DC static power converter which has an output current equals to n times the source current where n is the number of cells . After recalling the dynamical equations of the converter, its hybrid dynamical behavior and properties are highlighted. This particular hybrid system induces new and difficult control problems, such problem can be tackled by a new control concept based on Petri net. The PMC achieves an output current equal to n times the input current of the chopper, the major disadvantage of this type of converter is the imbalance branches of current with increasing number of cells. Therefore, modeling and control with Petri net is proposed to solve the problems of imbalanced of currents and the voltage output regulation with variation of the load. This approach is compared to the conventional PWM control.
