Abstract

In this paper, a high step-up boost converter with a non-isolated configuration is proposed. This configuration has a quadratic voltage gain, suitable for processing energy from alternative sources. It consists of two boost converters, including a transfer capacitor connected in a non-series power transfer structure between input and output. High power efficiencies are achieved with this arrangement. Additionally, the converter has a common ground and non-pulsating input current. Design conditions and power efficiency analysis are developed. Bilinear and linear models are derived for control purposes. Experimental verification with a laboratory prototype of 500 W is provided. The proposed configuration and similar quadratic configurations are compared experimentally using the same number of components to demonstrate the power efficiency improvement. The resulting power efficiency of the prototype was above 95% at nominal load.

摘要

本文提出了一种具有非隔离配置的高升压比升压变换器。这种配置具有二次电压增益，适用于处理来自替代能源的能量。它由两个升压变换器组成，包括一个连接在输入和输出之间的非串联功率传输结构中的转移电容。通过这种布置可实现高功率效率。此外，该变换器具有公共接地和无脉动输入电流。开展了设计条件和功率效率分析。为了控制目的推导了双线性和线性模型。提供了一个500W实验室样机的实验验证。使用相同数量的元件对所提出的配置和类似的二次配置进行了实验比较，以证明功率效率的提高。该样机在额定负载下的功率效率高于95%。
