Single-Inductor, Dual-Input CCM Boost Converter for Multi-Junction PV Energy Harvesting

Abstract This thesis presents a power harvesting system combining energy from sub-cells of

multi-junction photovoltaic (MJ-PV) cells. A dual-input, inductor time-sharing boost

converter in continuous conduction mode (CCM) is proposed. A hysteresis inductor current

regulation in designed to reduce cross regulation caused by inductor-sharing in CCM. A

modified hill-climbing algorithm is implemented to achieve maximum power point

tracking (MPPT). A dual-path architecture is implemented to provide a regulated 1.8V

output. A proposed lossless current sensor monitors transient inductor current and a time-based power monitor is proposed to monitor PV power. The PV input provides power of

65mW. Measured results show that the peak efficiency achieved ... (more)
