Direct torque control (DTC) can be applied to all AC machine drives. The synchronous motor torque control, based on DTC structure, permits to obtain high dynamic performances. DTC is a concrete solution to robustness and dynamic problems found in other control structures. In DTC scheme, the requirement of the continuous rotor position sensor and co-ordinate transformation is eliminated since all the calculation is done in stator reference frame. However; the DTC scheme requires the position sensor to determine the initial position of rotor at starting. Elimination of the shaft mounted position encoder is a very desirable objective in many applications as this sensor is often one of the most fragile components in the entire drive system. This paper presents the implementation of DTC to Permanent magnet synchronous motor (PMSM) with a sensorless initial rotor position estimation scheme. The requirement of sensor for the initial rotor position estimation can be avoided by impressing a high frequency voltage on the stator winding. The simulation results verify the effectiveness of the process.

This paper describes the design, implementation, and characterization of an Electronics Power Conditioner (EPC) with dynamic drain bias control that maintains efficiency of PA over a range of output power levels. The Drain voltage of power devices is varied in a known fashion against the input RF drive variations dynamically, to obtain better efficiency values over a range of output power. As a consequence, efficiency performances can be greatly improved as compared to classical back-off solutions. The employed 15-Watt C-band SSPA operates with 30% efficiency at an output power of 42 dBm. A coupler and detector from the PA provide a sample of RF input and a temperature detector provide the temperature data to the drain-bias controller, which is based on a buck dc-dc converter. The converter is designed with forward topology using resonant reset technique. Another low power push-pull converter is also used for providing housekeeping supply as well as low power supplies to the PA. When compared with a PA with constant drain bias (8V), the average efficiency of the PA with dynamic biasing is improved by 8.3%. Over an output power between 42-37.5 dBm, the drain bias varies from 8V to 5V, and the efficiency improves from 13.7 % to 22% at the lower power level. The efficiency figures include the losses in the dc-dc converter.

In all the PWM DC to DC and DC to AC converter topologies, the controllable switches are operated in switch mode where they are required to turn ON and OFF the entire load current during each switching. Here the switches are subjected to high stress and high switching losses that increases linearly with the switching frequency of the PWM. Another major significant drawback of switch mode operation is the EMI produced due to large di/dt and dv/dt caused by a switch mode operation. Therefore, to realize high switching frequencies in converters, the aforementioned shortcomings are minimized if each switch in a converter changes its status (from ON to OFF or vice versa) when the voltage across it and/or the current through it is zero at the switching instant. This paper propose a simplified switching scheme for three level full bridge DC to DC converters that enables zero voltage and zero current switching of all the main power devices. This describes the main operational modes of the converter as well as simulated results through MATLAB/Simulink.
在所有的PWM DC - DC和DC - AC转换器拓扑中，可控开关在开关模式下工作，在每次开关期间，它们需要打开和关闭整个负载电流。这里的开关承受高应力和高开关损耗，随着PWM的开关频率线性增加。开关模式操作的另一个重大缺点是由于开关模式操作引起的大di/dt和dv/dt而产生的电磁干扰。因此，为了在变换器中实现高开关频率，如果变换器中的每个开关在其上的电压和/或通过它的电流在开关瞬间为零时改变其状态(从ON到OFF或反之亦然)，则上述缺点将最小化。本文提出了一种简化的三电平全桥DC - DC变换器开关方案，实现了所有主电源器件的零电压、零电流开关。介绍了变换器的主要工作模式，并通过MATLAB/Simulink进行了仿真。

This These Mobile operators of Bangladesh are experiencing a fast growth of consumer market which has made it one of the highest growing areas of business. Power failure is a serious problem which the mobile operators are facing frequently and Diesel Generators (DG) are the common mean to tackle this problem. But constant increase of fuel price is a big concern for optimum operation of telecom Base Transceiver Stations (BTS). Therefore mobile operators are finding this system very cost ineffective and difficult to rely upon. Environmental issue is another major concern as burning diesel fuel increases emission of Carbon-Di-Oxide (CO2) and other harmful Greenhouse Gas (GHG). Renewable energy i.e. solar energy based solutions has the capability to overcome these aforesaid complications in context of Bangladesh. This paper gives emphasis on grid connected BTS sites powered by Solar PV (SPV) arrays along with DG's. The simulation of feasibility study and optimization analysis of proposed model has been performed using HOMER software. From the results of the simulation it is evident that SPV-Battery based systems are really cost-effective although requires a huge initial investment and at the same time they are much more environment friendly than the existing system.

This paper present a method to determine the optimal tuning of the PI controller parameter on Direct current (DC) motor drive system using particle swarm optimization (PSO) algorithm, Ziegler-Nichols (ZN) tuning and Modified Ziegler-Nichols (MZN) tuning method. The main objective of this paper is to minimize transient response specifications chosen as rise time, settling time and overshoot, for better speed response of DC motor drive. The speed control of DC motor is done using PI and PID controllers. Implementation of PID controller for DC motor speed control is done using ZN and MZN tuning method. For PSO algorithm technique, PI controller is used to improve the performance of DC motor speed control system. A comparison is made on the basis of objective function (rise time, settling time and overshoot) from output Step responses. The proposed approach had superior features, including easy implementation, stable convergence characteristic, and good computational efficiency. Fast tuning of optimum PI controller parameters yields high-quality solution. Compared with traditional ZN method and MZN method, the proposed method is found indeed more efficient and robust in improving the step response of DC motor drive system.

As a promising renewable alternative, the wind power is one of the significant source of generation. Reactive power compensation and harmonic reduction in a low voltage distribution networks for integration of wind power to the grid are the main issues addressed in this paper. This paper proposes a control scheme based on instantaneous pq theory for compensating the reactive power requirement of a three phase grid connected wind driven induction generator as well as the harmonics produced by the non linear load connected to the PCC using STATCOM. The proposed control scheme is simulated using MATLAB/SIMULINK. The Simulation results are also presented in this paper.

This paper presents the impact of changes in distance protection algorithm when performing simplifications in certain calculations. Advancements in digital technology have allowed relay manufacturers to include more and more relay functions within a single hardware platform. This paper presents digital power system protection implementation using dsPIC33F microcontroller using Fast Fourier Transform technique. The analog input signal is converted to its digital equivalent through a suitable 16-bit ADC and is further processed using complex Fast Fourier Transform algorithm to extract the fundamental frequency magnitude. Once this magnitude is obtained, it is fed to the internal relay algorithm to initiate appropriate actions. In this paper, implementation of distance relay using mho characteristic is explained.

Almost every electrical equipment is provided with insulation. The quality of insulation is very important factor in deciding the life of the equipment. Different methods had been used for assessing the quality of insulation under various conditions. Partial discharge (PD) test is one among the most important tests for assessment of insulation quality. In the paper, analysis of partial discharge is carried out for a void, inside the insulation with CIGRE-II method. A number of samples with different cavity dimensions have been prepared using circular Perspex disc. The analyses of these samples are done using MPD 540, which is a digital instrument, use for measurement of PD. By observations it is found that the inception voltage is almost 2.5 to 3.5 times the corresponding extinction voltage. By analyzing the graphs obtained for various parameters it is observed that the inception voltage decreases as diameter of cavity/cavity depth ratio or the diameter of cavity is increased, and it increases as cavity depth or sample thickness is increased.

This paper investigates the application of a Dynamic Voltage Restorer (DVR) to assist a wind turbine driven doubly-fed induction generator (DFIG) for uninterrupted power supply to the connected grid even under unbalanced grid voltage conditions. The DVR control is based on symmetrical components and vector control. Rotor Side Converter (RSC) is controlled to maintain stator active power and reactive power constant. Grid Side Converter (GSC) is controlled to maintain a constant dc link voltage. MATLAB/SIMULINK based simulation results for the test set up establish the effectiveness of the proposed control approach.
