Addressing the increasing demand for high-efficiency and high-power-density converters, flying-capacitor multilevel converter has shown itself as a promising topology. A key advantage of this topology is reduced voltage rating switches, though also makes it vulnerable to device failure during short-circuit conditions. Despite large interest in fault-tolerant operation these alongside detailed d...

Model predictive control (MPC) has been used widely in power electronics due to its simple concept, fast dynamic response, and good reference tracking. However, it suffers from parametric uncertainties, since directly relies on the mathematical model of system predict optimal switching states be at next sampling time. As a result, uncertain parameters lead an ill-designed MPC. Thu...

Quasi-2-level (Q2L) operation of multi-level bridge-legs, especially flying-capacitor converters (FCC), is an interesting option for realizing single-cell power conversion in applications whose system voltages exceed the ratings available semiconductors. To ensure equal voltage sharing among a Q2L-FCC’s switches, minimized flying capacitors (FCs) must always be balanced. Thus, we propose concep...

optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...

With the development of space exploration, high-power and high-voltage power systems are essential for future spacecraft applications. Because effects radiation such as single event burnout (SEB), rated voltage devices in converters a system is limited to level much lower than that traditional ground Thus, multi-level DC/DC good choices applications spacecraft. In this paper, fault-tolerant str...
