DSP based control for the new generation of complex convertors

The reduction of the electromagnetic interference and electromagnetic compatibility between power electronics devices as well as demand for high level of exploitation parameters lead to construction of more sophisticated systems which may contain more than one inverter. The paper deals with some aspects of the complex power electronic systems and control possibilities of the new generation of more sophisticated convertor topology. The aim of the proper control of such complex structures may be achieved with help of the new floating point DSPs. The family of Texas Instruments TMS320C3x DSPs opens a possibility of the direct, real time and integrated control of the complex structures with more than 6 power switches. A control algorithm has been implemented on the dSPACE DS1102 board equipped with a TMS320C31 processor and an adequate number of the analog and digital I/O ports. The results of the two step simulation as well as results measured using a real laboratory device are included and discussed.
