Control Of PV Integrated DAB Under Shading Conditions Using Improved Incremental Conductance MPPT Scheme

Abstract

The dual active bridge (DAB) topology is used to create a bidirectional DC-DC converter in this work.  The DAB is interfacing both Photovoltaic (PV) and battery. The phase shift modulation is considered as pulse width modulation (PWM) for the control of switches of DAB converters. The battery performance including voltage and state of charge (SOC) is analyzed using incremental conductance maximum power point tracking (MPPT) and the proportional and integral (PI) control. The dynamic operating condition including standard atmospheric condition and change of atmospheric condition is considered the performance evaluation of proposed work. The simulation results are presented and discussed under both charging and discharging condition of the battery.
