2014 Conference Paper Ka Rakhi, K. Ilango, Manjunath, H. Vb, and Nair, M. Gc, “Simulation analysis of half bridge series parallel resonant converter based battery charger for photovoltaic system”, in IEEE-International Conference on Power and Energy Systems: Towards Sustainable Energy Systems (PESTSE2014), Amrita School of Engineering, Bangaluru, 2014.[Abstract]

An innovative application of half-bridge series-parallel resonant converter (HBSPRC) for photovoltaic system and secondary battery interface is explained in this paper. This converter is designed for eliminating both low and high-frequency current ripples on the battery. This will helps to maximize battery life. The switching frequency greater than that of resonance frequency is preferred for operation, because the power switches turn on at zero current and zero voltage; thus, the freewheeling diodes need not have very fast reverse-recovery characteristics. Moreover the proposed battery charger circuit has a few components. To enhance the overall efficiency of the system energy conversion loss is to be minimized and the performance of the power converters depends upon the control method adopted. In this present work, Fuzzy logic based voltage controller and PI voltage controller have been designed, modeled and simulated in MATLAB/simulink platform and results are presented. © 2014 IEEE.

Developing efficient interfacing technologies to interconnect renewable energy sources with grid is a promising research area in renewable energy related applications. The interfacing unit becomes crucial as renewable energy sources when directly connected to grid, can inject harmonic components that may deteriorate the quality of power. This paper proposes a mechanism to use shunt active filter as an interface between renewable energy sources and grid with a modified and efficient control scheme. The shunt active filter with this modified controller controls the real power supplied by the grid (source) in addition to its usual functions such as reactive power compensation, power factor correction and harmonic elimination. Performance of the modified IcosΦ controller is compared with that of IRPT control algorithm. Two nonlinear loads are considered here namely AC voltage controller as soft starter for induction motor and a diode bridge rectifier feeding resistive load. Simulation of proposed system proves the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy systems. ©2012 IEEE.

2010 Conference Paper R. Mayuri, Sinnou, N. R., and K. Ilango, “Eddy current loss modelling in transformer iron losses operated by PWM inverter”, in 2010 Joint International Conference on Power Electronics, Drives and Energy Systems, PEDES 2010 and 2010 Power India, New Delhi, 2010.[Abstract]

Pulse width-modulated (PWM) inverters are used more and more to operate electrical machines and to interface renewable energy systems with the utility grid. However, there are abundant high-frequency harmonics in the output voltage of a PWM inverter, which increase the iron losses and result in derating of the machine or transformer connected to them. Predicting the iron losses caused by the PWM supply is critical for the design of electrical machines and transformers operated by PWM inverters. These losses are primarily attributed to eddy-current loss caused by the PWM supply. In this paper, after analyzing the harmonic components of PWM inverter voltage, the effects of different parameters of PWM switching on the eddy-current loss has been derived. The iron loss modelled with the proposed analytical methods on a three-phase transformer and is compared with the results of finite element analysis. This paper presents detailed equations for the prediction of iron loss. These equations can be directly applied in the design and control of PWM converters and electric motors to improve energy efficiency and reduction in total harmonic distortion in electrical machines and transformers operated by PWM converters.

2014 Journal Article D. Madathil, K. Ilango, Nair, M. G., and V.S. Kirthika Devi, “Voltage Flicker Mitigation in Electric Arc Furnace using D-STATCOM”, International Journal of Power Electronics and Drive Systems (IJPEDS), vol. 5, pp. 211–218, 2014.[Abstract]

The major power quality issue of voltage flicker has resulted as a serious concern for the customers and heavy power companies. Voltage flicker is an impression of unsteadiness of visual sensation induced by a light source whose luminance fluctuates with time. This phenomenon is experienced when an Electric Arc Furnace (EAF) as load is connected to the power system. Flexible AC transmission devices (FACTS) devices were gradually utilized for voltage flicker reduction. In this paper the FACTS device of Distribution Static Synchronous Compensator (D-STATCOM) is used to serve the purpose of mitigating voltage flickering caused by electric arc furnace load, which is efficiently controlled by Icosɸ control algorithm. The model of electric arc furnace is considered as a current source controlled by a non linear resistance, which had been simulated and performance was analyzed using MATLAB/SIMULINK Software.

<p>The grid integrated renewable energy sources are becoming a common area of interest for power generation in the recent times. The design and development of efficient interfacing technologies to interconnect renewable energy sources with grid is catching a lot of attention among the researchers these days. The interfacing unit becomes crucial as renewable energy sources when directly connected to grid, can inject harmonic components that may deteriorate the quality of power. This paper proposes a mechanism to use shunt active filter as an interface between renewable energy sources and grid with a modified and efficient control scheme. The shunt active filter with this modified controller controls the real power supplied by the grid (source) in addition to its usual functions such as reactive power compensation, power factor correction and harmonic elimination. The non-linear load is diode bridge rectifier feeding resistive load and the unbalanced load also introduced to verify the controller performance. The simulation of the proposed system under both balanced and unbalanced load conditions have been done and the obtained results prove the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy system.</p>
