High Voltage Gain Three Coupled Winding DC-DC Interleaved Boost Converter with Arduino Microcontroller for the PV Panel Control
摘要： In many applications, high-step converters are widely used, including powered vehicles, Photovoltaic (PV) systems, continuous power supplies, Gas lighting and fuel cell systems. The most important requirements in the energy conversion process are reliability, quality, maintenance and size reduction. This paper presents an Interleaved Boost Converter (IBC) to raise voltage gain with three coupled winding. This converter consists of three pairs of coupled inductors to collect energy in parallel and release energy to the series load, which provides a much higher output load voltage than the traditional DC-DC boost converter. To validate the performance, an investigation was introduced by means of steady state analysis and operation. The operation modes and mathematical analysis are presented. Arduino UNO microcontroller was used to implement Pulse Width Modulation (PWM) gate drive based on Maximum Power Point Tracking (MPPT). The DC-DC IBC with High Voltage Gain (HVG) produces low voltage stress across switches, low input and output current ripple, and also improves the efficiency. These features made this converter suitable for applications where a high voltage gain is demanded. This converter was tested using Matlab/Simulink to validate the performance in terms of input and output ripples. The results supported the mathematical analysis. The cancelation of the ripple in input and output voltages has significantly detected. The ripple amplitude is reducing in DC-DC HVG IBC comparing with traditional DC-DC boost converter, and the ripple frequency is doubled. This tends to reduce the output filter losses, and size. Also improves the efficiency of the converter.

摘要： This paper introduces a digitally controlled single-phase rectifier with power factor correction (PFC) based on a modified three-level boost converter topology. In comparison with the conventional boost-based systems, the new PFC rectifier has about three times smaller inductor and significantly lower switching losses. The improvements are achieved by replacing the output capacitor of the boost converter with a nonsymmetric active capacitive divider, with a 3:1 division ratio, and by utilizing the downstream converter stage for the capacitive divider’s center-tap voltage regulation. The nonsymmetric voltage divider and applied switching sequence effectively provide four-level converter behavior using the same number of components as three-level converters. As a result, a 66% reduction of the inductor compared to the conventional boost-based PFC and a 33% compared to the standard three-level solutions operating at the same effective switching frequencies are also achieved. Experimental results obtained with a 400 W, 200 kHz, universal input voltage (85 Vrms –265 Vrms ) PFC prototype demonstrate three times smaller inductor current ripple than that of the conventional boost converter allowing for the same inductor reduction. Efficiency improvements of up to a 6% are also demonstrated.

Enhanced Power Output from the PV with Low Input Ripple DC-DC Converter
摘要： The primary objective of Maximum Power Point Tracking (MPPT) for PV systems connected to a low-voltage DC grid is to extract the maximum possible power output from the PV array. Normally high-frequency switched mode power converters are employed to track the maximum power. These converters, however, impose switching frequency voltage ripple on the PV output. This causes fluctuation around the Maximum Power Point (MPP) and results in power loss. These losses can be reduced using electrolytic capacitors, however, the electrolytic capacitors’ lifespan is relatively shorter than that of a PV panel. In this paper, an interleaved boost converter is used to reduce high-frequency voltage ripple introduced on panel. Hence, smaller values of longer lifespan capacitors such as film capacitors will be sufficient to curtail the smaller ripple. Moreover, film capacitors are selected based on voltage ripple. Analysis was carried out for calculating voltage ripple imposed on PV module to select input filter more precisely. In addition, reduction in the voltage ripple is calculated quantitatively and is compared with that of a conventional boost converter. Enhanced power output from the PV panel is mathematically proven and experimentally demonstrated.

Direct Usage of Photovoltaic Solar Panels to Supply a Freezer Motor with Variable DC Input Voltage
摘要： In this paper, a single-phase photovoltaic (PV) inverter fed by a boost converter to supply a freezer motor with variable DC input is investigated. The proposed circuit has two stages. Firstly, the DC output of the PV panel that varies between 150 and 300 V will be applied to the boost converter. The boost converter will boost the input voltage to a fixed 300 V DC. Next, this voltage is supplied to the single-phase full bridge inverter to obtain 230 V AC. In the end, The output of the inverter will feed a freezer motor. The PV panels can be stand-alone or grid-connected. The grid-connected PV is divided into two categories, such as with a transformer and without a transformer, a transformer type has galvanic isolation resulting in increasing the security and also provides no further DC current toward the grid, but it is expensive, heavy and bulky. The transformerless type holds high efficiency and it is cheaper, but it suffers from leakage current between PV and the grid. This paper proposes a stand-alone direct use of PV to supply a freezer; therefore, no grid connection will result in no leakage current between the PV and Grid. The proposed circuit has some features such as no filtering circuit at the output of the inverter, no battery in the system, DC-link instead of AC link that reduces no-loads, having a higher efficiency, and holding enough energy in the DC-link capacitor to get the motor started. The circuit uses no transformers, thus, it is cheaper and has a smaller size. In addition, the system does not require a complex pulse width modulation (PWM) technique, because the motor can operate with a pulsed waveform. The control strategy uses the PWM signal with the desired timing. With this type of square wave, the harmonics (5th and 7th) of the voltage are reduced. The experimental and simulation results are presented to verify the feasibility of the proposed strategy.

摘要： In order to improve output performance, a two-phase six-state Pseudo-Continuous Conduction Mode (PCCM) interleaved boost converter for photovoltaic power generation systems is proposed in this paper. It not only retains the low-ripple output characteristics of the interleaved boost converter, but also has the characteristics of simple design and fast response. Dynamic-Reference-Current (DRC) strategy is used to reduce losses and improve efficiency. The dynamic reference current strategy is adopted to control the freewheeling loop switch tube to reduce the loss and improve the efficiency. The simulation results show that the fast-dynamic response and low output ripple are realized, and the feasibility of the DRC control strategy is also verified.

Improved hill climbing algorithm with fast scanning technique under dynamic irradiance conditions in photovoltaic system
摘要： The perturb and observe (P&O) algorithm is an easy and effective method used for tracking maximum power point. However, this technique suffers from deviation when irradiation changes suddenly. Moreover, the impact of this deviation is high when the insolation variation is rapid. This error is due to the incorrect decision taken by the conventional P&O method throughout the first step-change in the duty cycle during the increase in irradiation. The proposed P&O is a modified conventional P&O that focuses on using additional dI parameter with variable step size ?Dn. In this manner, the conventional P&O algorithm is allowed to identify the source of deviation caused by rapid irradiance changes. The efficiency of the proposed P&O is assessed using simulation in MATLAB/Simulink. Results show that the proposed P&O effectively tracks maximum power and prevents deviations in rapidly changing climate conditions within a short time, which is lesser than the conventional P&O method. In addition, the proposed P&O has a rapid dynamic response. A DC–DC boost converter is utilized in this work to validate the proposed P&O algorithm.

摘要： In this paper, we introduce a PV system consisting of a photovoltaic panel and a boost converter. The output of photovoltaic systems is not fixed. It varies according to the temperature of the solar cells and the solar radiation. Generally, the temperature and solar radiation is not constant and thus affects the output of our panel. Furthermore, we proposed a sliding mode control for our chopper, which will leads to the maximum power point tracking (MPPT). Therefore, we performed simulation tests under different environmental conditions and discussed the results to confirm that slip control was effective to the Perturb and Observe (P&O) method.

摘要： This work presents a nonlinear controller of a boost dc/dc power converter for photovoltaic (PV) maximum power point tracking (MPPT) systems. The scheme of the proposed controller consists of the design of a nonlinear controller for the duty cycle generation. For this purpose, a simple and low-cost voltage-oriented controller is proposed in this study. In fact, this control algorithm is suitable to efficiently track fast irradiance changes. Consequently, the efficiency of the overall MPPT system is improved by avoiding loss of PV power caused by i) oscillatory responses due to varying irradiance conditions and ii) load disturbances. In addition, by assuming passivity properties of the constitutive relationship of the load element, internal stability of the closed-loop system is guaranteed for different load conditions, which are applicable for most PV applications. Besides, the internal stability allows to consider load scenarios affected by bounded disturbances. Finally, the proposed MPPT control system is implemented by using a proportional-integral-derivative controller, thereby providing a low-cost solution, which is programmed in the TMS320F28379D DSC Board. Experimental results by considering several scenarios, i.e., i) irradiance changes, ii) changes of setpoint and iii) load disturbances are illustrated to validate the effectiveness of the proposal.
