The comparison involved,. In PWM methods such as sine-triangle PWM, three phase reference modulating signals are compared against a common triangular carrier to generate the PWM signals for the three phases. In SVPWM methods, a revolving reference voltage vector is provided as voltage reference instead of three phase modulating waves. The magnitude and frequency of the fundamental component in the line side are controlled by the magnitude and frequency, respectively, of the reference vector. The highest possible peak phase fundamental is very less in sine triangle PWM when compared with space vector PWM. Space Vector Modulation (SVM) Technique has become the important PWM technique for three phase Voltage Source Inverters for the control of AC Induction, Brushless DC, Switched Reluctance and Permanent Magnet Synchronous Motors.

The sample used consists of 40 students of class X studying the Physics of CBSE curriculum. Data is collected based on essay, class room discussion and Viva-Voce. From the results of this paper it can be concluded that the students do not understands the real and actual concepts of ohm's of by merely reading the curriculum books and by performing the experiments in school lab. The results also reflect that the misconception may also arise due to the misinterpretation of language of physics in relation to electro properly. This paper is the reflection of teaching ohm's law in the classroom in which the students generally gets confused and develops the wrong concepts at secondary and senior secondary level. The results, discussion and conclusion in this paper will also help the teachers to develop the students' insight into the nature of physics.

This paper presents modelling and simulation of Dynamic Voltage Restorer (DVR) with pi controller using MATLAB/SIMULINK. One of the major power quality problems of sag is dealt in this paper which is harmful for the industrial customers as it causes malfunctioning of several sensitive electronic equipments. DVR is Custom power Device (CPD) which provides the series compensation in the electrical network to improve voltage disturbance in electrical distribution system. The proposed scheme allows flexibility in cost and simplicity in design. Simulation results are also illustrated to understand the performance of DVR under voltage sag fault condition.

Now-a-days Industrial loads are generally based on Power electronic devices which are very sensitive to voltage disturbances. Hence it is mandatory to provide high quality power supply since; failures due to these power quality issues have adverse effect on production time and cost. The Dynamic Voltage Restorer (DVR) is most important Custom Power Device (CPD), with its effective and reliable dynamic capabilities, when connected in between load end and source end, can compensate for voltage sag and hence maintaining the line voltage to its nominal value. This paper depicts the modelling and simulation of DVR with Neural Network controller to mitigate the voltage sag in industrial and electrical distribution system. The proposed controller provides optimal mitigation of voltage sag. Simulation is performed using MATLAB/Simulink; to demonstrate that DVR maintains the load voltage level to the nominal value by injecting a suitable voltage level during the occurrence of voltage sag.

The session was conducted for three days at one of the day schools in Indore, The Delhi Public Elementary School. The qualitative and quantitative methods were used and the presentation session was conducted for the teachers to analyse the skills of group of 30 teachers. The finding of the study reflects that there is a drastic build in confidence, attitude and perception of the teacher before and after the micro teaching session was conducted. A questionnaire and an interview session was also conducted at the end of every presentation and the finding shows that teachers believed that this session gives a chance to understand their weakness and strength related to their professional teaching. The results also reflect that the teachers were able to establish the skills of: planning, demonstratio...

In present scenario modern industrial devices and devices in electrical distribution system are mostly based on devices such as electronic drives, microprocessors and programmable logic controllers (PLC) etc. These devices are very sensitive to power quality disturbances. Hence it is required to provide a high quality output power to these devices for their satisfactory operation. Failing to provide a good quality output power to the industrial load may affect the loads badly and sometimes may lead to the complete shutdown of particular equipments or complete industry which results in major financial loss to the industry concerned. So stable, reliable, defect free and high quality uninterruptible power supply must be guaranteed from the supplier or utility side. But the blame for degraded power supply must not be solel...
