摘要

本文介绍了一种用于光伏应用的高效升压变换器的研制。该设计旨在创造一个完全独立的单元,能够将太阳能转化为电能。最初的目标是建立一个可以提供稳定的24 V/sub dc/输出的设备,从光伏阵列的波动直流连接输入电压。这种升压变换器的典型应用是为并网或独立系统的逆变器提供直流电源。利用仿真软件PESIM对设计拓扑进行优化操作。采用UA3843A芯片实现了规格指标。研制了120 W变换器,最大输出电压纹波为1.2%,效率达到85%以上。

Development of high efficiency boost converter for photovoltaic application
In this paper, a development of high efficiency boost converter for photovoltaic application is presented. The design aimed to create a completely self-contained unit capable of converting light energy from the sun into electrical energy. The initial goal was to build a device that could provide a stable 24 V/sub dc/ output, from a fluctuating direct current-linked input voltage from the photovoltaic array. The typical application of this boost converter is to provide a DC power supply for inverter either for grid connected or standalone system. To perform the optimum operation for the design topology the simulation software PESIM was utilised. The chip UA3843A was used in order to get the specification target. The 120 W converter has been developed with 1.2% of maximum output voltage ripple and the capability of efficiency is achieved more than 85%.
