Abstract

A multiple-input boost (MIB) converter is proposed to implement maximum power point tracking (MPPT) for series strings of solar cells, typically connected across bypass diodes in photovoltaic (PV) modules. The proposed configuration is intended to increase energy harvest from the PV module during instances of partial shading. Results from an experimental prototype demonstrate that the MIB converter extracts up to 9.6 % more power compared to a single-input boost converter in a 120W PV module. The proposed topology can be adopted in emerging distributed MPPT system architectures that utilize microconverters and microinverters.
