Software Implementation of Lowest Level Control for FB-MMC Converter
Kokeš, Petr
For FB-MMC converter (Full Bridge Cell, Modular Multilevel Converter), the software implementation of SA-PWM modulation (Sampled Average PWM) and SORT-BAL sorting type balancing of cell voltages have been designed. The report deals with the specifics of realizing control methods using the Beckhoff TwinCAT 3 system. The control structure was divided into explicitly defined function blocks for the Master controller as well as for the distributed EPX Slave units. Data transfer timing between the Master and the Slave units has been designed and the synchronization of EtherCAT link communication has been tested in practice. \n
