Stand-alone Photovoltaic Power Generation System Design

Solar energy is the most abundant resources of renewable energy. Has unique advantages and great potential for the development and utilization of, and take full advantage of solar favor to maintain the harmony of man and nature and the coordinated development of energy and environment. The human early use of solar light and heat. The emergence of photovoltaic technology has opened up a vast area for solar energy utilization. Since the1990s, the development of the solar photovoltaic power generation will soon have been widely used in the field of aerospace, communications, transportation, and residents of remote areas of life.The article from the hardware circuit and a control circuit for photovoltaic system analysis and design. At the same time, the use of Matlab simulation analysis on the maximum power point tracking control circuit. This article provides methods and means for the realization of high reliability and high conversion efficiency, may play a crucial role in the implementation of photovoltaic systems, reducing system cost.Mainly from the following sections focus on:First,the main circuit device selection basis, and given the focus on the protection of the power device IGBT. Then, from the hardware circuit design of the inverter to several links:the overall structure of the system design requirements to the system, the device comparative selection, schematic. The entire hardware circuit system includes a main circuit, the power circuit, the driver circuit. The selection and design of the Boost circuit, full-bridge inverter circuit, select the relevant parameters.Second,the maximum power point tracking circuit Boost boost circuit, and full-bridge inverter circuit control strategy analysis, comparison, and selection.Third,the system circuit related software design, while using Matlab/Simulink draw the simulation model, and the maximum power point tracking circuit Boost boost circuit, and full-bridge inverter circuit is simulated and analyzed.
