Applying Parks Transformation to a single to three phase convertor
Proceedings of PESC '95 - Power Electronics Specialist Conference, 1Co-Authors: M. Malengret, G. Naldrett, J. EnslinAbstract:Single to three phase converters are readily available, however, the proposed converter allows for output voltage regulation. The convertor utilises a three phase transformer in conjunction with a reduced size inverter. The converter is particularly suitable for rural electrification, with the transformer performing the dual role of stepping down the voltage as well as being an integral part in the single to three phase conversion. It is shown how balanced regulated three phase can be achieved and therefore improve quality of supply. >

Unit Template Synchronous Reference Frame Theory Based Control Algorithm for DSTATCOM
Journal of The Institution of Engineers (India): Series B, 2014Co-Authors: J. Bangarraju, V Rajagopal, A JayalaxmiAbstract:This article proposes new and simplified unit templates instead of standard phase locked loop (PLL) for Synchronous Reference Frame Theory Control Algorithm (SRFT). The extraction of synchronizing components (sinθ and cosθ) for Parks and inverse Parks Transformation using standard PLL takes more execution time. This execution time in control algorithm delays the extraction of reference source current generation. The standard PLL not only takes more execution time but also increases the reactive power burden on the Distributed Static Compensator (DSTATCOM). This work proposes a unit template based SRFT control algorithm for four-leg insulated gate bipolar transistor based voltage source converter for DSTATCOM in distribution systems. This will reduce the execution time and reactive power burden on the DSTATCOM. The proposed DSTATCOM suppress harmonics, regulates the terminal voltage along with neutral current compensation. The DSTATCOM in distribution systems with proposed control algorithm is modeled and simulated using MATLAB using SIMULINK and Simpower systems toolboxes.

Designing a Controller Circuit for Three Phase Inverter in PV application
2018 International Conference on Electrical Electronics Communication Computer and Optimization Techniques (ICEECCOT), 2018Co-Authors: Tanushree Bhattacharjee, Majid Jamil, Anup JanaAbstract:In this paper a three phase voltage source inverter (VSI) has been simulated with controller circuit that can be used in future for hardware implementation using dSPACE 1104 controller in photovoltaic application. The dSPACE controller can be used, as it can link the MATLAB Simulink model directly into a real time operating prototype. The switching of IGBTs will be controlled by generating sinusoidal pulse width modulation (SPWM) signals with proportional integral (PI) controller circuit and Parks Transformation. The three phase inverter ac output voltage will be stabilized with the help of controller circuit attached to it in simulation model. Here DC voltage source is taken as the photovoltaic generator that supplying power to the three phase inverter. With this model the simulation output is showing a result of 2.83% of total harmonic distortion and supports that the controller circuit used is improving inverter ac voltage output to a great extent. This control system can be transformed into a prototype model with the dSPACE controller board as suggested in this paper.
