光伏发电系统中高升压比DC-DC变换器
High Step-Up Ratio DC-DC Converter for Photovoltaic Generation System
摘要
Abstract
Photovoltaic(PV) generation system is an important application for the use of solar energy and attracts more and more attention. It usually contains a former DC-DC converter and an afterward inverter. Single-phase inverter output voltage is typically 220 V(AC), so the former DC-DC converter need to reach a high step-up ratio, which is out of the capability of the single-stage converter. A two-stage structure with a Boost converter and a full-bridge converter is used in this paper. Moreover, the LLC resonant network is introduced to the full-bridge converter for the further improvement of performance. Two 1 kW prototypes of DC-DC converter are built in the lab for comparison. The experimental results verify the theoretical analysis and satisfy the design requirements.关键词
