A New Single Phase 5- Level Inverter Fed from Hybrid Renewable Energy System with Less Number of Switches
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Renewable energy sources such as photovoltaic, wind, and low-head hydro and geothermal are expected to increase greatly their market share of the total power produced in the world. Fuel cell technology is also nearing the development point where it could start to supply a significant share of the power needs. For high-voltage electrical systems multilevel inverters have been developed to overcome shortcomings in the ratings of solid-state switching devices. The distinct structure of multilevel voltage source inverters permits them to get high voltages with less harmonic content and transformer less operation. This forms these distinct power electronics topologies suitable for custom power and flexible ac transmission systems (FACTS) applications. The use of a multilevel converter to control the real and reactive power flow at a dc/ac interface, frequency, voltage output (including phase angle), provides significant opportunities in the control of distributed power systems. In this paper new system architecture for hybrid photovoltaic and wind energy system connected to the grid. Depending on their availability this method permits these renewable energy sources to deliver the load together or independently. This proposed five level multilevel inverter uses less switches when compared with the conventional Multilevel Inverter.
