Abstract
Concentrated Photovoltaic (CPV) systems provides a potentially low-cost and high-efficiency alternative to conventional mono-crystalline Si panel PV systems, and a new CPV system with Laterally-Arrayed Multi-Bandgap (LAMB) cells is introduced. In this thesis, an IC-based Multi-Input Single-Output (MISO) power converter, which serves as the small-footprint and self-powered power management module of the CPV system, is designed and tested. The proposed converter shall efficiently harvest energy from 4 types of solar cells and track the Maximum Power Point (MPP) at the cell-block level. First, the circuit topology, MPP Tracking (MPPT) algorithm, and control mechanism are verified with discrete converters, then a qualitative demonstration is conducted outdoors to show the concept of the entire CPV system with power management. Finally, a first-generation integrated converter, with the passive components, Analog/Digital converters and a MPPT-enabling micro-controller off-chip, is implemented.
