[IEEE 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - Kannur,Kerala, India (2018.3.23-2018.3.24)] 2018 International Conference on Control, Power, Communication and Computing Technologies (ICCPCCT) - Four Switch Three-Phase Inverter Fed Induction Motor for Economical and Efficient Stand Alone Solar Water Pump
摘要： Induction motors are commonly used in industries due to its reduced cost and minimum maintenance. In this proposed system induction motor is used for the purpose of solar based water pumping application. As the energy consumption is increasing, the energy generated is alone is not able to supply the entire load requirement. Among the available renewable energy sources, solar energy is the leading one. The work proposes a three-phase four-switch inverter for photovoltaic (PV) water pumping or treatment systems. The use of batteries can be avoided, since the converter used in this proposed work is two inductor boost converter. By considering the economic factor and life span of the device, electro-chemical storage elements are avoided. Also an effective intelligent hill climbing algorithmis used to extract maximum power from PV cell. The use of a three- phase induction motor is a better solution to the dc motor for water pumping application.

Co-Design of the PV Array and DC/AC Inverter for Maximizing the Energy Production in Grid-Connected Applications
摘要： Grid-connected Photovoltaic (PV) systems are currently developed by merging a PV array and a DC/AC inverter which are designed separately, without considering the impact of the PV array operational characteristics on the power losses of the DC/AC inverter. In this paper, a co-design technique is presented, where the optimal design parameters of the PV array and DC/AC inverter in a grid-connected PV system are calculated concurrently through a unified design process. The proposed technique enables to optimally match the PV array configuration and the DC/AC inverter structure. A study has been performed, where the PV systems synthesized by applying the proposed co-design technique are compared with PV system configurations comprising PV arrays and DC/AC inverters that have been designed separately, through distinct optimization processes based on various alternative optimization objectives. The design results for two installation sites, with different meteorological conditions during a year, demonstrated that only the proposed co-design optimization technique is capable to ensure the maximization of the annual energy production of the overall grid-connected PV system.
