Paper Title
Solar Power Converter With MPP Tracking Accuracy For Dc Microgrid Applications”
Abstract
The DC microgrid applications include
rural electrification, UPS support, Electronic lighting
systems and Electrical vehicles. The overall system
consists of a Photovoltaic panel (PV), High step up
DC-DC converter with Maximum Power Point
Tracking (MPPT) and DC microgrid. The whole
system is mainly optimised with both MPPT and
converter separately. Here the incremental
conductance technique is used for maximum power
point tracking technique modified with D-Sweep
(Duty ratio Sweep). D-sweep technique reduces the
problem of multiple local maxima. Converter
optimization includes a SEPIC converter for DC-DC
conversion and a full bridge inverter for DC-AC
conversion. Both converter optimization and MPPT
optimization increases overall system efficiency. The
maximum power conversion efficiency of the system
is 95.85%.
