Abstract
Electrical discharge machining (EDM) is a process under which giving different shapes to hard metal, hole and simultaneously forming. The objectives of this paper work to investigate of various reviews of authors which works on behave during operation with different types of tool material and also investigate influences. This paper elaborates about the manufacturing condition aspects to take into consideration in the majority of process and particularly in process related to Electrical Discharge Machine (EDM).There are the conditions that determine important characteristics such as material removal rate, Electrode wear. By means of the improvement and growths in new machineries, low weight & high strength, high hardness and temperature resistant materials have been advanced for distinctive applications which include aerospace, medical, automobile and more. In the machining of hard and metal matrix composite materials, outdated manufacturing processes ar

Abstract
In this paper a fuzzy controlled active damper circuit is introduced in a grid connected inverter system with instability issues. An adaptive active damper can be connected to the point of common coupling (PCC), which can automatically regulate a virtual resistor to the critical value to stabilize the system. Furthermore, a harmoniccurrent-reference compensation method is adopted to make the active damper more accurately simulate the virtual resistor in a wide frequency range. This paper investigates the harmonic-current-reference compensation for the stationary α−β frame, synchronous d−q frame, and decoupled synchronous d−q frame-controlled three-phase adaptive active damper. With the proposed method, the active damper controls the active and reactive power directly and improves the stability of the grid-connected inverters under weak grid at the same time. The simulation of the proposed system with PI and FIS controllers are carried out in MATLAB Simu

Abstract
In this paper a Unified Power Quality Controller is connected to a test system with harmonics and voltage variations creating sags and swells in source and load voltages. The UPQC is supported with PVA connected at the DC link injecting active and reactive powers to the grid. Individual controllers are modelled for shunt and series converters with feedback from the source and load voltages and currents. Both the converters work in synchronization to the source voltage with SRF controller using sinusoidal PWM technique. An MPPT is also used for magnitude generation of the reference current. For further improvement in the model the conventional sinusoidal PWM is replaced with space vector PWM reducing the harmonic content in the source voltages and currents. The design is modelled in MATLAB Simulink environment with graphs generated with respect to time
