| Abstract |
This paper presents the implementation and dynamic analysis of synchronous frame current regulators for Modular Multilevel Converters (MMC) using complex vectors. This includes the design of the Decoupling Physical Input Cross-Coupling (DPICC) for MMC-topologies. With this, the set of differential equation of the MMC can be transformed into the same format that is used for virtually every other Voltage Source Inverter (VSI) and thus in terms of current control the MMC can be controlled with similar control strategies. Limitations in the performance of common synchronous frame Proportional plus Integral (PI) control techniques are demonstrated. The design of a proportional plus time-weighted accumulation current controller in the discrete time domain is also laid out in this paper. |
