摘要： In the following paper, the Proportional-Integral (PI) controller of the DC-DC boost converter are tuned with and without using the accelerated particle swarm optimization algorithm (APSO) and the performance of the converter is analyzed under the effect of the variable irradiation level of the photovoltaic (PV) module. The mathematical modeling of the photovoltaic module is implemented in the MATLAB/Simulink having two variable parameters, temperature and irradiation level to change the output of the module. The output of the PV module is fed to DC-DC boost converter having a particular value of the duty cycle ratio to increase the voltage to the desired constant value. A three phase sinusoidal pulse width modulation (SPWM) inverter having DC link voltage coming from the converter’s output is simulated in the MATLAB/Simulink and a three phase resistive load is connected across the output terminals of the inverter to get phase and line voltages of the inverter. The irradiation level is used as a variable parameter having a step change at regular intervals and the output voltage of the DC converter under the close feedback system is observed. A comparison is made between the tuning parameters of the PI controller calculated with and without using the Accelerated particle swarm optimization algorithm.

Improved Restricted Control Set Model Predictive Control (iRCS-MPC) Based Maximum Power Point Tracking of Photovoltaic Module
摘要： This paper presents a robust two stage maximum power point tracking (MPPT) system of the photovoltaic (PV) module using an improved restricted control set model predictive control (iRCS-MPC) technique. The suggested work is improved in two aspects; a revision in conventional P&O algorithm is made by employing three distinct step sizes for different conditions, and an improvement in conventional MPC algorithm. The improved MPC algorithm is based on the single step prediction horizon that provides less computational load and swift tracking of maximum power point (MPP) by applying the control pulses directly to the converter switch. The computer aided experimental results for various environmental scenarios revealed that compared with the conventional method (conventional P&O + MPC), for the PV power and inductor current, the undershoot and overshoot is decreased to 68% and 35% respectively under stiff environmental conditions. In addition, the settling time needed to reach a stable state is significantly reduced in the proposed system. The viability of the solution suggested is verified in MATLAB/Simulink and by hardware experimentation.

Robust Direct Adaptive Controller Design for Photovoltaic Maximum Power Point Tracking Application
摘要： Tracking the maximum output power of a photovoltaic (PV) cell is an important problem to harvest more energy at di?erent weather and load conditions. This paper presents the design and simulation of a robust direct adaptive controller (RDAC) for maximum power point tracking (MPPT) device based on boost converter topology. A mathematical model is developed, and a suitable RDAC is designed for MPPT device, and simulations are performed using MATLAB/Simulink to verify the controller’s robustness at varying operating conditions. The real-time irradiance and temperature data are used on an hourly basis to test the suggested MPPT adaptive controller for a typical sunny day in summer and winter. The simulation results show that the RDAC performs excellent tracking under varying conditions such as irradiance, temperature, load, boost converter inductance, and capacitance.

摘要： This paper is a review on 4 phase 8/6 switched reluctance motor (S RM) powered by solar PV array using the buck-boost dc-dc con verter. The water pumping system is operating S RM. The main objective of this paper is to regulate the speed of S RM dri ve to pump the water through the DC link voltage of a mid-point converter. The split capacitor con verter for S RM dri ve called as mid-point converter is electronically commutated is inexpensive, reliable and efficient than conventional DC and AC electrical machines used in this application, because of its simple construction. The losses in mid-point converter can be reduced by using S RM drive at its fundamental frequency and also the efficiency of the proposed system can be increased. The DC-DC buck-boost con verter is working in continuous conduction mode (CCM). The CCM operation decreases the losses of DC-DC converter. The soft starting of 4 phase 8/6 S RM drive is also achieved through proper selection of step-size in incremental conductance (InC) algorithm method of maximum power point tracking (MPPT). The DC-DC buck-boost con verter is the unique converter which allows excellent tracking of PV array maximum MPP rather than of temperature and insolation levels.

A cm-Scale 2.4-GHz Wireless Energy Harvester With NanoWatt Boost Converter and Antenna- Rectifier Resonance for WiFi Powering of Sensor Nodes
摘要： The widespread use of WiFi in the 2.4-GHz ISM band creates the potential for RF powering using WiFi radios. This paper presents the design of a cm-scale RF-energy harvester including antenna, rectifier, and dc–dc boost converter for RF powering in the 2.4-GHz ISM band. The rectifier and boost converter are designed while considering cold-start operation and nanowatt-scale available power from the rectifier for RF incident power <?33 dBm. Low-power design in the power management unit and converter leads to ～1-nW quiescent power. The harvester implementation in 65-nm CMOS occupies 1.6 mm2 while the antenna occupies 1.27 cm2. The proposed design optimization approach leads to a sensitivity of ?33 dBm in cold start and ?36 dBm in the primary mode for 1-V output, translating to ～1.4× and ～2× improvement in range compared to prior art. Measurements using a commercial WiFi TX demonstrate the ranges of up to 1.25 m for 14-dBm output power with 1.3% TX duty-cycling in WiFi access-point mode, demonstrating the feasibility of powering sensors from RF power beacons in the 2.4-GHz ISM band as well as from background WiFi transmissions.

A Comparative Topologies in Grid Connected Photo Voltaic System for Efficient Behavior
摘要： The power delivered by a PV system consisting of one or more photovoltaic cells is dependent on the irradiance, temperature, and the current drawn from the cells. Maximum Power Point Tracking (MPPT) is used to obtain the maximum power from these systems. Grid-tied inverters are the key components of distributed generation system because of their function as an effective interface between renewable energy sources and utility. In this paper, Perturb and Observe (P&O) and Incremental Conductance (IC) MPPT controllers are modeled and comparison is carried out. Recently, there has been an increasing interest in the use of transformer less inverter. The leakage current issues of transformer less inverter depends on the topology structure and modulation scheme, so it have to be addressed very carefully to meet the safety regulations. In order to eliminate the leakage current, OH5transformer less inverter topology is proposed and compared with switching inverter. The results concluded that using ICalgorithm the efficiency will improve comparatively. With the use of transformer less OH5 inverter along with ICalgorithm reduction in size and cost is observed. The improvement in efficiency with OH5 inverter is possible because of using five MOSFET switches. With usage of MOSFET switches switching losses and dead time is reduced. The leakage current is less in OH5 inverter compared to all other topologies proposed in reference. So isolation between grid and PV system is possible and safety of operating person is improved.

摘要： This paper discusses the comparison of fuzzy and adaptive neuro-fuzzy controllers to control PV inverter interfacing with grid. The PV interfacing with a novel seven level converter is operating under grid unbalance. The proposed converter has the capability to reduce number of power electronic devices and power consumption. The time delays take place with filters can be easily extracted by using both conventional and proposed controllers. The main problem with fuzzy controller is that rules are not consistent; there is a possibility of mismatch between the rules. In order to extract these problems the methods used in neural networks are applied to learn the rules in fuzzy, which results an adaptive control technique and is named as adaptive neuro-fuzzy controller (ANFIS). The multilevel inverter is actively controlled by ANFIS to compensate time delays, harmonics. The proposed system is developed and simulated to evaluate the performance under different operating conditions.

摘要： In this work, we use the Backstepping controller with integral option to track the maximum power point of a photovoltaic (PV) system. The controller is applied in three cases of the solar panel. In the first case the PV without resistances: series and shunt resistances, while in the second case the PV with series and shunt resistances, the third case consist of PV with constant series resistance, and therefore, shunt resistance values are changed up to plus 50%, without forgetting the variation of the weather conditions solar irradiation and temperature, to check whether the controller is rigor and robust enough. The system under study contains PV associated to a load via DC/DC Boost converter, and we have a Backstepping control design integrated the integral option added to ameliorate the strong control performance of nonlinear controller. The Backstepping strategy for getting the optimal power point and system stability is used Lyapunov’s analysis. The system and the control method is analyzed with a simulation model that was based Simulink/Matlab.
