The applications of DC-DC converter are fast increasing. This converter converts voltage from one level to another voltage level. Power level value also ranges from small to high level. But due to fast development in DC to DC converters number of topologies are available. This paper analyzes two different converters; Boost converter and SEPIC converter. The theoretical derivations and parameter equations for designing the DC-DC converters are presented. The workconcentrates on variation in the input parameters like inductance, capacitance and switching frequencyto obtain the desired output voltage. The output voltage ripple is also calculated for comparing the two converters. Further, the performance parameters such as total harmonic distortion, power factor are calculated for that particular converter. The DC-DC converter performance of the simulation was carried out in PSIM Software.

In this manuscript, tuning rules are proposed for conventional series and parallel cascade control structures with emphasis on stable processes. Both primary and secondary controllers are assumed as proportional-integral (PI) type and are designed using the method of moments (MOM). In MOM, the controller parameters are computed by comparing the corresponding derivatives of the expected and actual closed-loop transfer functions at $s=0$. Moreover, equations relating closed-loop time constants and maximum sensitivity are also obtained. Despite of its simplicity, the proposed method yields robust and superior closed-loop performance.

Wind and solar are the renewable technologies which are very popular and well known source of energies throughout the world. Fossil fuels are formed by natural processes which contain a high quantity of carbon include coal, natural gas and petroleum which comes under non-renewable energy sources. Wind and solar Energy Forecasting is done to estimate the output power and energy of renewable energy sources. Forecasting is done at regular intervals to balance the supply and demand of energy. Solar and wind power forecasting are completely depends on metrological parameters such as velocity and direction of the wind, temperature, and humidity As solar and wind variability is stochastic, many of statistical models along with linear and non-linear models such as ARIMA, kalman filters, ANN, and support vector machines respectively used to catch the randomness of solar and wind energy. Lot of disadvantages are there for various approaches along with its computation complexity and incapability to alter the time varying time-series systems. This paper provides a comprehensive review of the theoretical forecasting methodologies for both solar and wind energy and also merits and demerits of different methods. The study of time series prediction of solar and wind power generation mainly focus on reviewing the advantage of using Long-Short Term Memory (LSTM) and Recurrent Neural Network (RNN).
风能和太阳能是可再生能源技术,是世界上非常流行和众所周知的能源来源。化石燃料是由自然过程形成的,含有大量的碳,包括煤、天然气和石油,它们属于不可再生能源。风能和太阳能预测是对可再生能源的输出功率和能量进行估计。定期进行预测,以平衡能源的供应和需求。由于太阳和风的变化是随机的,许多统计模型以及线性和非线性模型(如ARIMA、卡尔曼滤波、人工神经网络和支持向量机)分别用于捕捉太阳能和风能的随机性。各种方法都存在计算量大、不能改变时变时间序列系统等缺点。本文对太阳能和风能的理论预测方法进行了全面的综述,并对不同方法的优缺点进行了比较。太阳能和风力发电的时间序列预测研究主要集中在回顾长短期记忆(LSTM)和循环神经网络(RNN)的优势。

This work proposes a charging system using split phase supply for electrically driven vehicles. The proposed configuration uses a PWM converter and an integrated bidirectional buck-boost converter as a charger which has lesser number of switches than other conventional chargers. Split phase systems will be normally used with unbalanced loads due to which there will be unbalanced source currents existing in the system. The main objective of this work is to reduce the unbalanced currents and also to eliminate the harmonics thereby achieving sinusoidal source currents with unity power factor in the split phase system for which a constant DC voltage control is used. The behavior of the system with the proposed control algorithm is analyzed and validated using MATLAB & Simulink based simulation.

Excess loop delay compensation using RZ DAC for the third order CT ΔΣ modulator with CRFB-FF structures 采用RZ DAC对三阶CT ΔΣ CRFB-FF结构调制器进行过量环路延迟补偿

Continuous-time Delta-Sigma Modulators (CT-DSM) suffer from one of the system-level non-idealities called an excess loop delay. This excess loop delay changes the NTF (Noise Transfer Function) and affects the stability of the modulator. Return-To-Zero DAC (RZ-DAC) solves this problem if the delay value is ranged between 0 and 0.5. Adding an additional path around the quantizer compensate the excess loop delay for the range 0.1 to 1. But this requires the delay value to be known before. A simple technique for compensating excess loop delay for any unknown delay values up-to 1 is suggested in this paper. The compensation technique uses RZ-DAC with an additional compensation loop with delay $mathrm{z}^{-1/2}$ and a simple modification around the quantizer. To verify the compensation technique the third order CT-DSM with CRFBFF structure has been chosen. The modulator achieves constant S(Q)NR of 87. 4dB with loop delay up-to 1 in the signal chain.
连续时间δ - σ调制器(CT-DSM)存在系统级非理想性,即过量环路延迟。这种多余的环路延迟改变了NTF(噪声传递函数)并影响调制器的稳定性。如果延迟值在0到0.5之间,则归零DAC (RZ-DAC)解决了这个问题。在量化器周围添加一个额外的路径来补偿0.1到1范围内多余的环路延迟。但这需要事先知道延迟值。本文提出了一种简单的补偿任何未知延迟值大于1的多余环路延迟的技术。补偿技术使用RZ-DAC和一个额外的补偿环路,延迟$ mathm {z}^{-1/2}$和围绕量化器的简单修改。为了验证补偿技术的有效性,本文选择了具有CRFBFF结构的三阶CT-DSM。调制器实现恒定的S(Q)NR为87。4dB,环路延迟在信号链中高达1。

The energy requirement is rising due to the increase in the number of population, high development and some rural upliftment projects and schemes. However, the traditional power sources are getting narrowing down and increased worry causing depletion of the ecosystem has led to the search for better and safer non-conventional sources of energy which can contribute to a safe, pollution free and clean environment. Wind, solar and Hydro energy are the substitute energy supplier in this regard. This article performs a technique for electricity generation with the use of water energy, using a Savonius turbine which is an excellent replacement in the interest of creating a better, safe and clean environment. The simulation is carried out in Matlab environment and results are presented and found that the Savonius turbine offers a promising solution for power generation.

The dynamic electromechanical linear modeling of Switched Reluctance Motor is effectuated mathematically by MATLAB/Simulink software tool. This SRM an electrical machine rotates having salient pole rotor and stator, wherein concentrated phase windings are present in stator poles and there are no windings present on the rotor poles. The two coils of SRM phase as a mandate is located at the opposite poles. This is a three phase machine with 6 Stator pole pairs and 4 rotor pole pairs (6/4 motor). In this Simulink model of switched reluctance motor an Electrical model has been delineated for three phases individually and then this electrical energy is converted to electromechanical energy by collectively connecting the three phase electrical model to the Mechanical model. Simulations are catalogued by corresponding Matlab parameters. In this paper the electrical processes and the rotational motion of the SRM phase is illustrated. The torque expression extrapolates Switched Reluctance Motors salient features and its implicated operation. The SRM computer model is developed exercising the simulation package of Matlab software, the SRM phase is connected to the resistance is simulated as a controlled current source. The SRM mathematical model generated by MATLAB/ Simulink is elucidated.
