A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. Depending on the input/output voltage transfer characteristics, the schematics, the operation quadrant, and control, SMRs possess many classifications and application. Typical potential application examples include grid powered motor drives, ...

Ensuring a protection scheme in DC distribution system is more difficult to achieve against pole-to-ground faults than AC because of the absence zero crossing points and low line impedance. To complement major obstacle limiting fault current, several compositions have been proposed related mechanical switching solid-state switching. Among them, circuit breakers (SSCBs) are considered be possibl...

<span>In DC microgrids, the utilization of renewable energy results in disruptions. This paper proposes coordinated control multiple batteries using a fuzzy logic controller (FLC). The goal is to regulate voltage and power on microgrid. Method used with modified coupling configuration. proposed new topology uses 2 photovoltaic (PV) arrays. Part PV array output will be stored battery, part...

This article proposes coordinated model predictive control (MPC) techniques for a DC-coupled hybrid microgrid system with solar photovoltaic and wind generated system. To achieve optimum power generation in the microgrid, finite-control-set MPC (FCS-MPC) controls both PV-wind using DC-DC converter controlled rectifier. The mathematical formulation of proposed is described, maximum point trackin...

Isolated bi-direction DC-DC converters are widely used for energy storage systems (ESS) of DC microgrids. Particularly, a current-fed isolated bi-directional converter (CF-IBDC) receives much attention due to its merits such as the naturally attenuated current ripple on battery side. However, high efficiency cannot be obtained at light and heavy load conditions under conventional control method...
