Modak PG Student Department of Electrical Engineering Government College of Engineering, Aurangabad, Maharashtra, India. gmodak82@gmail.com Dhote V. P. Assistant Professor Department of Electrical Engineering Government College of Engineering, Aurangabad, Maharashtra, India. vpdhote@gmail.com Abstract— Due to the increasing demand of electricity and the limited conventional energy resources, Solar Photovoltaic energy becomes a favorable alternative as it is pollution free, freely available and has less maintenance cost. This paper presents basic steady state analysis of Zeta Converter by using State Space Averaging Method in continuous inductor current mode. The Zeta converter is a fourth order DC-DC converter which is capable of operating in Buck and Boost Mode. The Zeta Converter is cascaded between Solar Photovoltaic Panel and Load. The input voltage to Zeta converter is fed by a photovoltaic panel. The modeling of solar panel is done by considering the design equation of photon current and reverses saturation current. The objective of this paper is to analyze the performance of Zeta converter by a change in Temperature, Irradiance, Duty Cycle and Load Resistance. The effectiveness of model with the result is verified by using simulation done in MATLAB TM Simulink. Keywords— Continuous Inductor Current Mode (CICM), Solar Photovoltaic (SPV), State Space Averaging (SSA), Zeta Converter. I. INTRODUCTION The India is a second largest populated country in the world. The population is increasing day by day. So to meet the required energy demand we have to move towards Renewable Energy Resources. Environment gets polluted due to Non Renewable Energy resources such as Coal, Diesel etc. They are major cause of production of Green House gases which are responsible for the global warming and depletion of ozone layer [6]. Non Renewable Resources are dying. So it’s necessity to use the freely available Renewable Resources such as solar, wind, geothermal etc. Out of this, the solar energy is the best alternative for the energy generation also it has advantages such as its freely available, environmentally friendly, less maintenance and operational cost [1]. Every Renewable energy system has its different method to generate the electricity. Most of the systems require power electronics converters which are the main essential part of the system. In photovoltaic energy generation system, DC to DC converters is used. The various types DC-DC converters used in solar photovoltaic system are Buck, Boost, Buck-Boost, Cuk and SEPIC [5]. Each DC-DC Converter has its own operating methods and characteristics. Each DC-DC converter has advantages and disadvantages over the others [11, 12]. The advantages of Zeta Converter over the other Converters are non-inverting polarity, low settling time, less switching stress and adaptability [1]. The sun is the huge source of energy. The earth receives a 174000*10 12 watt of incoming solar irradiation at the upper atmosphere [1]. The Solar radiations changes at different time at a specific location. So the power generated by solar photovoltaic is varying in nature. The Loads requires a constant power or constant input. so it's necessary to drag maximum power from the solar photovoltaic. The maximum power point tracking is mostly used method for solar photovoltaic [8, 9, 10]. This paper is organized as, the operation of Zeta Converter is explained in Section-II. The Modeling of Zeta Converter by using SSA method and Photovoltaic panel in Section-III. The simulation and Results are described in Section-IV and the Conclusion of this work in Section-V. II. OPERATION OF ZETA CONVERTER A Zeta converter is a nonlinear system converter of fourth order. The basic circuit diagram for non-isolated Zeta converter as shown in Fig. 1(a) On the basis of switching on off condition the operation is divided into two modes. Mode-I] The converter operates in Mode-I when switch “S” is ON (closed). The equivalent circuit for this mode-I shown in Fig.1(b). During this mode, the switch S is closed the two inductors namely L 1 and L 2 are in charging mode. The inductor L 1 is charge by source. Here assumed that the capacitor C 1 and C 2 are already charge. The capacitor C 1 charges the inductor L 2 and provides continuous current to the 978-1-5090-5682-8 /17/$31.00 ©2017 IEEE
