Matlab Simulation on Photovoltaic Boost Half Bridge Multilevel Inverter System Using Mppt
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
In order to achieve low cost, easy control, high efficiency, and high reliability this project presents a novel Photovoltaic boost half-bridge multilevel inverter system using repetitive current control and maximum power point tracking (MPPT) with its control implementations. A boost half-bridge dc-dc converter using minimal devices is introduced to interface the low voltage PV module. A multilevel pulse width modulated inverter is cascaded and injects synchronized sinusoidal current to the grid. More over a plug in repetitive current control is proposed to control the grid current. A customized maximum power point tracking (MPPT) method which generates a ramp-changed PV voltage reference. High power factor and very low total harmonic distortions are guaranteed under both heavy load and light load conditions. Maximum power point tracking (MPPT) and repetitive current controller is used to improve the performance and efficiency. The Simulation is done and Photovoltaic boost half-bridge multilevel inverter results are connected to grid.
