Abstract:

© 2019 IEEE. This paper presents a multiport magnetic-link based T-type multilevel inverter topology and associated control scheme. The proposed structure comprises of series stacked AC-DC modules connected to a high-frequency magnetic-link, which boost the input DC-link voltage level significantly, and generates the required dc-link voltages for the multilevel inverter stage. The desired number of the output voltage level can be realized by cascading series stacked AC-DC modules and bidirectional switches. Due to inherent voltage balancing capability of the magnetic-link based structure, this topology does not require any control scheme to balance the series connected capacitors in the DC-bus. Thus, it reduces the control complexity. Moreover, the magnetically isolated structure eliminates the leakage and DC current injection into the grid from DC sources, like photovoltaic (PV) module. The proposed structure has the capability to integrate multiple sources operating with different voltage levels, and consequently, reduces the number of components and control complexity. In this work, multilevel voltage synthesizing, active and reactive power control capability are realized by using the finite control set model predictive control (FCS-MPC) algorithm. A prototype multilevel inverter incorporating three stacked AC-DC modules, designed for seven levels operation has been built and tested to verify the circuit performance and associated control scheme.
