IET Power Electronics, EarlyView., 2023 This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...

Robust and Fast Voltage-Source-Converter (VSC) Control for Naval Shipboard Microgrids [PDF]
IEEE Transactions on Power Electronics, 2019 This letter proposes a new modified model predictive control (MPC) to compensate for voltage and frequency deviations with higher bandwidth for an ac shipboard microgrid (MG). The shipboard power system (SPS) and islanded MGs have a reasonable analogy regarding supplying loads with local generations.
