ATX power supply derived MPPT converter for cell phone charging applications in the developing world

Recently, a new method has evolved for the recovery of materials in Waste Electrical and Electronic Equipment (WEEE) namely, the repurposing of constituent components for second life. Such an approach is opposed to the traditional raw materials harvesting that is the norm, which in the majority of cases leads to the destruction of serviceable parts together with all other non-recycling materials. This paper presents a novel photovoltaic system suitable for disparate population centres in the developing world utilising repurposed components from discarded computer power supplies.
