A load matching system which utilizes a time-sharing controller for an standalone solar PV system employing a Dual Input/Output Biphase Buck dc–dc Converter is presented here. The load matching system consists of an integrated load voltage and MPPT controller to regulate power flow between a standalone dc load, solar PV and a battery. The Dual Input/Output Biphase Buck dc–dc Converter incorporates the advantages of both multiport converters used for standalone systems and the multiphase converters used for low voltage and high-current applications. The steady-state analysis of the proposed system is performed by deriving the appropriate analytical equations and computing using the MATLAB programming language. A dynamic model of the Dual Input/Output Biphase Buck dc–dc Converter is developed and has been used for simulating the dynamic performance of the proposed load matching system. The efficacy of the proposed load matching scheme was also validated through experimentation under various operating conditions.
