In modern power converters the PWM strategy shows the major concern in reduction of switching losses and Total Harmonic Distortion (THD). In high power traction drives, the switching frequency has to be reduced to limit the switching losses, as it becomes difficult to arrange cooling for the inverter if the switching losses are huge. Usually the maximum switching frequency is limited. There are many PWM techniques available to reduce the THD in inverter output among them Space Vector Pulse Width Modulation (SVPWM) gives better performance than any other techniques. Due to flexibility in the choice of switching state in SVPWM, there can be possibility of the six different SVPWM strategies, each having good performance at particular range of modulation index. By using all six strategies a new hybrid SVPWM strategy has been developed and the performance is compared with other PWM techniques for v/f drive of maximum switching frequency 450HZ with MATLAB13a.

Most of the developing countries are facing electrical power shortage. High cost of the fossil fuels, their rapid depletion and adverse impact on the atmosphere has led to the intensive research in the field of renewable energy. Various renewable energy sources such wind, solar, bio-mass are already exploited. Hydro power is also a renewable energy source. Small hydro power plants below 5 KW capacity which are known as Pico-hydro power plants are becoming popular due to their inherent advantages. This paper presents laboratory test results of a 3.5 KW induction motor operating as a self excited induction generator. Effect of excitation capacitor on the performance of the generator is discussed. Authors have fabricated and tested a 200 watt Pico-hydro generation unit using a water wheel at actual site. Design procedure of a water wheel is explained.

The optimal tuning of the Proportional-Integral-Derivative (PID) controller gains, for enhancing performance of industrial Permanent Magnet DC (PMDC) motor, based on Particle Swarm Optimization (PSO) is presented in this paper. The main aim is to minimize performance specifications, such as, steady state error, rise time, maximum overshoot/undershoot and settling time. The proposed method is applied to the linear model of PMDC motor. Performance of the suggested objective function of PSO is compared with the performance of other objective functions of PSO and conventional Ziegler Nichols (ZN) method. This comparison clearly indicates the effectiveness of proposed objective function.

The need to store and transmit ECG signal data is continuously increasing. Due to limited storage capacity and limited transmission bandwidth, there is a need to compress ECG signal. This paper involves review of existing ECG compression methods and enhancements are proposed to simplify them for portable ECG recorder. The portable devices or embedded systems have limited computing/processing power. The enhancements are suggested to reduce complexity of the algorithms to make them compatible for embedded systems. The proposed method is evaluated on the basis of different compression and quality parameters like compression ratio (CR), percent root mean square difference normalized (PRDN) and quality score (QS). The PRDN is an important parameter as it indicates the error introduced. The compression algorithm includes three sequential processing phases: 1. Pre-processing and classification, 2. Linear transformation, 3. Entropy coding. The ECG compression method is analyzed with different quantization factors like 0.5, 1, 2 and 4. The de-compression technique is the inverse process of compression and it reconstructs the original signal with negligible loss of information. Finally, the described method is compared with existing ECG compression algorithms.

It is important for the distributed generators in the Microgrid to ensure reliable power supply to the loads when integrated into the grid. When connected to grid, each distributed generator works in constant current control mode in order to provide a set power to the load. When the distributed generator is cut off from the grid, each distributed generator must detect this islanding situation and must switch to constant voltage control mode. In this mode, the distributed generator will provide a constant voltage to the local load. This paper reviews a control strategy used for a generator to implement grid-connected and intentional-islanding operation of a Microgrid. It has been simulated in MATLAB. The performance of the system has been validated for unity and lagging power factor load. This control strategy has been used for analyzing the power flow between the Microgrid and the large grid.

This paper presents the optimum utilization of renewable energy sources existing in India. In renewable energy sources wind mill and photovoltaic cell plays an important role in India. The available wind velocity and solar radiation and climate plays important role in Indian power sector. Increasing demand of electricity it is very important to develop micro-grids to diversify the generation. So to solve this problem and optimization of wind and solar power are necessary. To optimize power in wind mill venture tube is designed to produce more power by extracting power from the wind and maximum power point tracking (MPPT) i.e. Perturb and Observe (P & O) technique is utilized to extract more power from PV cells. Venture effect in wind mill and MPPT technique is used to form DC Micro-grid and implemented in MATLAB as well as hardware results are tested. Results show the better operating performance of micro-Grid in stability issue and optimum power extraction from the wind mill and solar cell.
