Abstract
Multilevel Modular Cascade Converters (MMCC) can be used to provide higher effective switching frequencies and reduce harmonic distortion in classical converter problems such as BESS and STATCOM. To successfully implement a MMCC in a STATCOM application it is necessary to balance dc-link voltages of the individual modules and track a reference output current. This work presents master and individual module controls utilizing feedback linearization and sliding mode control. Simulation results demonstrate that the control strategy presented in this paper can balance dc-link voltages of individual modules and provide output current tracking within the first cycle.
