Multilevel Inverter is an array of power semiconductors and capacitors that allow the generation of a high quality load voltage. But it requires greater number of power semiconductor switches with increase in number of levels. In this paper, three phase hybrid topology of multilevel inverter is used to reduce the number of switching devices in the entire converter system. The proposed topology is a hybrid of cascaded H-bridge multilevel inverter (CHBMLI) and neutral point clamped inverter multilevel inverter (NPCMLI) so as to obtain seven level output in each phase. Third harmonic injection is adopted to increase the line to line voltage. Asymmetric dc bus voltage ratio is used to increase the number of levels. The main objective of this hybridised structure is to increase the number of levels with reduced number of switches.

Nowadays, low Power Factor (PF) is a serious problem that gained more importance in power electronics area. In this paper, single phase PFC using Buck-Boost circuit topology under linearization voltage control is realized. Here the nonlinear load considered is the diode bridge rectifier, and a Buck-Boost converter is connected to its back end for PFC. The switching of buck-boost converter is done by comparing the dc control signal with a saw tooth wave and its switching frequency is set to 100 kHz. The simulation analyses are carried out in Matlab/Simulink software. The effect of PFC Buck-Boost circuit on PF and the sinusoidal nature of line current are analyzed by the simulation results. Its effectiveness is experimentally validated by means of a self designed prototype. Experimental results show that, Buck-Boost circuit topology have an excellent ability for PFC. It makes the supply voltage and current in phase to each other and thus approximate the PF to unity.

The stator flux and electromagnetic torque are directly controlled in a DTC system using space vector modulation technique. In DTC, torque and flux ripples increases at low speeds. A DTC-SVM induction motor drive at very low speeds is investigated here and High Frequency Signal Injection (HFSI) method is adopted to mitigate the low speed issues. In this method a sinusoidal wave of small amplitude and high frequency is injected along with the PI controller output of DTC-SVM. HFSI increases the switching frequency of SVM during low speed operation. This technique reduces torque ripple, acoustic noise, and gives excellent dynamic and steady state performance. The performance of DTC-SVM and DTC-SVM with HFSI at low speed is analyzed through simulation using matlab/simulink package. The results verify the merits of the DTC-SVM using HF injection technique with respect to DTC-SVM technique at very low speeds.

Electrical impedance measurement of the biological samples has evolved as a new field in biomedical engineering. This is due to the fact that the electrical properties of the biological samples change considerably during diseased and healthy conditions. Unfortunately, the devices available in the market are bulky and are quite costly. In this study, we report the development of a portable, standalone, multi-frequency (50 Hz-10 KHz) impedance measurement device with acceptable accuracy and resolution for in vitro impedance measurement of the cells.

The proposed paper presents a Hybrid AC-DC microgrid to chop the process of multiple conversions in an individual AC microgrid or DC microgrid. The proposed hybrid microgrid compose of both AC microgrid and DC microgrid connected together by multilevel inverter. This paper concentrates on developing a control system for the hybrid AC-DC microgrid to manage power flows, which is more difficult than previously developed systems only for AC microgrid or DC microgrid. The objective is then to makeup a co-ordinated control system for power sharing within the sources in the hybrid AC-DC microgrid in proportion to the power ratings. The droop control technique is presented in this paper to control the hybrid microgrid. The droop control concept uses a suitable normalization technique for combining both the subgrids. The co-ordinated operation of DC and AC sources and multilevel inverter are investigated. Analysis of power sharing on hybrid AC-DC microgrid is done using MATLAB/SIMULINK.

Modelling of Electric Vehicle power train is analysed to evaluate the energy flow between electrical and mechanical sub systems. The indigenous platform SEQUEL gives more user configurability and new user element support for offline simulation. State-of-the-art real-time simulation facilitates the controller development and evaluation before making the plant prototype of system like EV. Because of the high frequency switching in power converter/inverter and due to complex motor dynamics detailed simulation of EV power train need high computation with simulation delta time of the order of 1-2 micro sec. This is practical in offline simulation where as presently available real-time simulators can do simulation in 50-100 micro seconds only. So the concept of average modelling is introduced in EV sub-systems to derive appropriate models to implement real time simulation.

Centrifugal Pumps are used in the primary and secondary heat transport systems of fast reactors for pumping liquid sodium. Lubrication oil leakage from the conventional bearings used in these pumps is a potential threat to cause reactivity changes which could result in extended reactor shut down. Actively controlled magnetic bearings which do not require lubrication is an excellent alternative to conventional bearings in overcoming these problems. The present work deals with the development of “Thrust and Radial Active” magnetic bearings for a small centrifugal sodium pump of 50 m3/h capacity, which controls both the axial and radial movements of rotor. The developed active magnetic bearing takes a thrust load of around 100kg, and a nominal radial load for the existing vertically-configured shaft system of the centrifugal pump. Performance of the active magnetic bearings has been tested successfully by running the pump up to the full operating speed of 2900 rpm and the measured vibration levels were well within the allowable limits of ISO 14839.

Detection of human face from an image is a very difficult process. There are many reasons that affect the detection process such as lighting condition, shadows, facial expression etc. Thus facial feature extraction itself becomes a difficult task. In order to propose an efficient method for facial feature extraction, we used the characteristic features of nostrils, eyes lips etc. In our method we assume that frontal face image is readily available. At first face regions detected by detecting the eye regions. After detecting the face region other feature points such as nostril, corners of eyes, corners of lips etc are extracted. At first eye pairs are obtained by finding and verifying possible eye regions. After detecting the eye regions, the distance between the eyes is used to find a possible face candidate. Next, the face is divided into different regions and facial features are extracted from the corresponding regions.
