Input-series-output-parallel (ISOP) connected DC-DC converters enable low voltage rating switches to be used in high voltage input applications. In this paper, a DSP is adopted to generate digital phase-shifted PWM signals and to fulfill the closed-loop control function for ISOP connected two full-bridge DC-DC converters. Moreover, a stable output current sharing control strategy is proposed fo...

Connection of distributed generation (DG) units, energy storages, and new loads into low voltage (LV) grids leads to a constrained operation of the grids. Consequently, voltage limits violation and overloading of grid assets occur more frequently. To tackle these issues, distribution system operators (DSO) still employ traditional techniques in planning distribution grids to increase grid hosti...

In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...

Abstract UPS can provide stable electrical energy for sensitive loads when severe grid disturbance happens. A neutral point clamped (NPC) three-level voltage source converter is used as the circuit topology UPS. In this study, discrete mathematical model of derived and a single loop control strategy based on predictive presented. The proposed method has simple structure fast response speed omit...

In recent years, voltage source multilevel converters are very popular in medium/high-voltage industrial applications, among which the NPC/H-Bridge converter is a popular solution to the medium/high-voltage drive systems. The conventional finite control set model predictive control (FCS-MPC) strategy is not practical for multilevel converters due to their substantial calculation requirements, e...

In a conventional AC distribution system, the conservation voltage reduction (CVR) strategy is widely employed to lower down of specific load power consumption. The wide applicability demand side management (DSM) using CVR in stand-alone microgrid through VSI-based energy sources thrust area, that is, not examined yet and needs be explored. fast dynamics flexible control are characteristics vol...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...
