    Abstract: The objective of this study is to quantify the energy loss due to snow on solar photovoltaic systems. Solar photovoltaic systems in cold temperatures have an advantage over warmer regions due to improved efficiencies. However, colder regions generally receive a significant amount of snow, which may hinder the energy output of the photovoltaic syste... Show More

    Abstract: Based on the existing AC-AC switched-capacitor (SC) converter, this paper demonstrates a new cascaded AC-AC converter circuit topology with a ratio of 1/2n, which only consists of power switches and capacitors. The converter consists of multi-stage converters and the pre-and post-stage circuits are independent with each other. The principle of the ... Show More

    Abstract: In solar photovoltaic (PV) system it has been a tendency to extract the maximum output power from the PV panel with the decrease of production price. There are many novel control algorithms to track the maximum power point. The commonly used control algorithm is based on perturbation and observation algorithm (P&O). However, the traditional P&O met... Show More
