The purpose of this work is to use fewer components to generate more output levels for power interfaces of low dc voltage sources such as fuel cells. First, two switched‐capacitor voltage lifters (SCVLs) with similar structure and same function are summarized. Each of them uses a single capacitor and has the advantage of identical voltage stress for all components. Then, the SCVLs are combined with a T‐type unit to develop two 17‐level inverters. The SCVLs is responsible for voltage boosting, while the T‐type unit uses two flying capacitors to increase the number of output levels. In addition to the use of three capacitors, the two 17‐level inverters employ 13 and 14 semiconductor switches respectively, and all components' voltage stresses do not exceed the dc input voltage. Simple structure, reduced capacitors' count, and low components' voltage stress are the main merits of the proposed inverters compared with other 17‐level inverters. Beyond theoretical analysis, both steady‐state and dynamic performances are verified experimentally, and the highest efficiency measured by the experiment is up to 97.8%.

“…Doubly fed induction generator (DFIG) is commercially employed for wind energy generation; it is employed and discussed in details for wind solar autonomous generation by various authors (Elbeji et al, 2014a;Gandomi et al, 2019;Hamed and Elbeji, 2017;Khoshkbar Sadigh et al, 2017). DFIG is advantageous with regard to its operation and control by low power rated converters for variable wind speed input (Abhishek et al, 2018).…”

In this paper an islanded microgrid fed through the wind and solar energy resources is presented. The power flow within the microgrid is controlled using a Neutral Point Clamped Dual Active Bridge (NPC-DAB) converter. In the proposed dc microgrid, the solar energy source is associated at the low voltage (LV) bus and the wind energy source is connected at the high voltage (HV) bus. A permanent magnet synchronous generator (PMSG) machine is used in wind energy conversion system. The real time solar radiation and wind speed data of Rupangarh, Rajasthan, India is used as an input for renewable energy resource. The NPC-DAB will work as a power electronics juncture for expediting the energy exchange in the islanded DC Microgrid. The proposed closed loop controller based on the capacitor voltage and load voltage will expedite a complete automatic operation of the islanded DC-microgrid considering various load changes. The system is studied without storage element as the automatic control of energy generation and load feeding is carried out by the NPC-DAB, also this makes the scheme cost effective. The optimum duty ratios for NPC-DAB operation are obtained and thus the increased load demand is met. The modeling of PMSG, NPC-DAB and wind energy system is discussed in details in this work. The proposed system is studied in MATLAB/Simulink environment and results are obtained for different load variations. All the wind control parameters, NPC-DAB waveforms, load waveforms are also plotted using MATLAB.
