Abstract: This work develops a PV and battery-operated hybrid power management scheme (HPMS) through a single capacitor-based multi-input converter (SCMIC). The proposed SCMIC integrates the PV and the battery of two different voltage levels through unidirectional and bidirectional circuital arrangements, respectively. The output DC link voltage is maintained at a steady reference level by controlling the discharging and charging operation of the battery, which successfully balances the power difference between the load and the available maximum power from the PV. The mathematical modelling of the proposed converter is developed in this work. A power management and control architecture is designed to meet the objectives of PV MPPT and the bidirectional power flow operation of the battery. The proposed system is implemented in simulation and real-time environments under several scenarios. The simulation results demonstrate the efficacy of the proposed system in all the operating conditions. The real-time performance of the system validates its simulation counterparts.
