The water pumping performance of two wind-electric systems is compared to the water pumping performance of two solar-PV systems. The wind-electric systems were rated at 1.0 kW and 1.5 kW at a wind speed of about 12 m/s, and the rotor diameters were 2.75 m and 3.05 m, respectively. The solar-PV systems were rated at 0.1 kW and 0.9 kW at a radiation level of about 1000 W/m2, and the total solar panel surface areas were 1 and 17 m2, respectively. Both wind-electric systems powered three-phase 230 V a-c induction motors with centrifugal pumps. The smaller of the solar-PV systems powered a d-c motor with a diaphragm pump, and the larger one powered a single phase 230 V a-c induction motor with a centrifugal pump. Only a well pumping depth of 30 m was evaluated for both wind-electric and solar-PV water pumping systems. The 0.1 kW and the 0.9 kW solar water pumping systems can provide enough water for 25 and 75 cattle, respectively, if the incident solar radiation is similar to that of Bushland, TX. The 1.0 kW and 1.5 kW wind-electric water pumping systems can provide enough water for 300 and 400 cattle, respectively, if the wind regime is similar to that of Bushland, TX.

Voltage Feedback

This paper proposes a single inductor dual output (SIDO) DC-DC converter with an exclusive control circuit. We propose two kinds of converter: a buck-buck and a boost-boost converter. Multiple voltage outputs are controlled exclusively, using error voltage feedback. This approach requires a few additional components (a switch, a diode and a comparator), but requires no current sensors and does not depend on the value of output voltage or output current. We describe circuit topologies, operation principles and simulation results.

Power Point

The purpose of this article is to extract the maximum power point at which the photovoltaic system can operate optimally. The system considered is simulated under different irradiations (between 200 W/m<sup>2</sup> and 1000 W/m<sup>2</sup>), it mainly includes the established models of solar PV and MPPT module, a DC/DC boost converter and a DC/AC converter. The most common MPPT techniques that will be studied are: "Perturbation and Observation" (P&amp;O) method, "Incremental Conductance" (INC) method, and "Fuzzy Logic" (FL) control. Simulation results obtained using MATLAB/Simulink are analyzed and compared to evaluate the performance of each of the three techniques.

The Difference

Investigation of on-board renewable solar PV and wireless EV charging station integration is studied in this paper. Integration of on-board solar PV power with EV charger power will reduce the stress on the grid without the need for extra ground for solar plant installation. A dual-input buck-boost converter (DIBBC) is used to integrate the two power sources and charge the EV battery. A small-signal model of the converter is used to design the controller for three switches of the DIBBC. The simulation model of the integrated solar PV system and wireless power transfer (WPT) system is designed for charging a battery of 120V/165Ah at 130V. The hardware prototype of the proposed EV battery charging system is designed for 1.5kW to verify the simulation results. WPT system is developed for circular spiral-shaped coils, which are series-series compensated for 85kHz resonance frequency. Solar PV is replaced by a solar simulator programmed to operate with the same specifications used in the simulation. Results and analysis of the DIBBC based charger with charging voltage 130V showed higher efficiency up to 92% when both the sources are supplying power to DIBBC. The proposed charging system gives better efficiency with higher source voltages and when the difference in power supplied by the two sources is less. Thus, higher voltage sources are beneficial for improving the efficiency of the integrated charging system. Further, loss analysis in major components of the converter is discussed.

This paper presents a new selective switching strategy for single phase SPWM Inverter that can reduce the power loss and total harmonic distortion. Power loss is always a command issue for inverter system. Power loss occurs during the switching of the inverter. This new selective switching strategy is modified from the typical switching strategy and has been proven to reduce the power loss and harmonics. This project had already been tested on direct power source and also from the solar PV module. This project is focusing on 100W inverter system.

Simulation Results

In this paper, the characteristics of AC/DC converter under single-phase voltage sags and three-phase voltage sags are simulated with Matlab emulator. The simulation results show that effects on rectifier equipment under three-phase voltage sags are more serious than those under single-phase voltage sags. The flat wave capacitance plays an important role in voltage sensitivity of sensitive loads. In practice, the capacitance of flat wave capacitor is chosen according to the power supply and load requirements so as to realize the best balance of performance and price.

This study primarily focuses on the design of an intelligent three-phase soft-switching mode rectifier (SSMR). Firstly, the small-signal dynamic model of a single-phase SSMR is derived together with the design of its controller. Then, the developed single-phase SSMR is connected to form an intelligent three-phase SSMR. When any of the phase modules in the proposed intelligent three-phase SSMR experiences a fault, it can continue to supply power automatically under reduced load capacity while still maintaining good power quality characteristics. Finally, some simulation results were used to demonstrate the effectiveness of the proposed intelligent three-phase SSMR design.
