High power demands are usually met by advanced power electronics converters in several large utility and electric drives applications. Applications from high power drives commonly uses solution based multi pulse and multilevel converters. A common DC link with atleast one voltage source converter (VSC) working with almost fundamental switching frequency are used in converters of multipulse type, and each output module is connected with the multipulse transformer in series. When compared to that of solution with single-VSC, Several VSCs generating different triggering pulses are adjused in order to achieve current injected with low specified total harmonic distortion (THD) with losses of abridged switching. Huge structure in complexity and expensive cost expenditure of the multipulse transformer is the major limitation of this scheme. DC link split capacitors in addition are eliminated by modifying the topology of the circuit. Thus, the independent voltages of the DC capacitor are controlled and decreased in number and the flow of third harmonic current component in the transformer is eliminated. The scheme of the designed controller is depending on the derived mathematical system model. Simulaion observation is used to check the scheme performance and efficiency in a detailed way with drive control technique.

Abstract. The Classical PI controllers have been imperatively preferred for the control action of the active compensators in a power distribution system. However, the performance of these controllers is affected greatly by varying parameters and uncertainties in modeling and also high stability issues. In other side fuzzy logic based PI controllers have more robust and accurate appearance. The main intention of this work is to analyze and implementation of an adaptive intelligent controller for DSTATCOM for the expedited in-phase vectorial formulation template with mamdani fuzzy structure. The in-phase de-opposition of the current wave injected by the compensator is able to enhancing power quality features at PCC level. The efficient performance of robust adaptive fuzzy algorithm for the PI gain values are to be controlled by the operation of DSTATCOM. It enforce the non-adaptive control actions in terms of expressive dynamic response, inferior steady state error and achieve good stability with the appreciate dynamic behavior of adaptive intelligent type DSTATCOM under Matlab/Simulink tool.

“…The RES may be an AC source such as wind energy generation or a DC source such as PV array & fuel cell with high rated converter coupled to dc-link. Hence, the energy generated from the proposed renewable energy source needs power conditioning like high rated converters to get high voltage as well as energy conversion before connecting to conditioner [5] [6]. To minimize the intricate of the premature conditioner combination, the converter type series active power filter, which comprise very high impedance for high-frequency harmonics, is consort by a shunt resonant type passive power filter to furnish a way for the harmonic currents of the distributed load, permits an ameliorate all over the performance of plain series active filter based conditioner and the extended their capabilities to include voltage & current harmonic elimination.…”

With a sprit use of non conventional energy generating sources, photovoltaic (PV) array installations are constitute increasingly engaged in so many applications, like distributed energy generation and stand-alone systems, grid connected systems to improve the power quality features. A specific and simple control method is suggested for compensating and improving power quality problems. This paper take part the energy utilizing phenomena occurring in linear power system network differentiate the unbalanced load condition, mitigation of harmonics, and compensating the reactive power. The control strategy is based on the vectorial dual formulation of instantaneous power theory, so that the voltage waveform injected by the active filter is able to compensate the reactive power and the load current harmonics and to balance asymmetrical loads, regulate the voltage profile when disturbances coming from the grid and achieving load condition. The proposed algorithm also improves the bear of the passive filter and also auto tune up the series active power filter maintains to get THD substantially within IEEE-519 standards. The proposed method is enormously evaluated with improved dynamic behavior of HMFC Topology using MATLAB/SIMULINK Platform.
