摘要

本文提出了一种双端口DC-DC变换器，并结合了一种改进的反激逆变器。逆变器的输出是230V的正弦电压，50Hz，用于供应农村照明应用。太阳能-电池混合系统的DC-DC转换器的两个输入端口是能源(太阳能和电池)的组合以及电压倍增器。为了获得负载的低频输出电压，采用了改进的反激逆变器结构。本文还提出了一种控制算法，实现了光伏电源和蓄电池电源分别供电或同时供电，以保持输出电压恒定。本文重点对该变换器进行了仿真研究，利用PSIM软件验证了变换器的有效性。

Two-port DC-DC converter with flyback inverter for rural lighting applications

A two port DC-DC converter, combined with a modified flyback inverter, is presented in this paper. The output of the inverter is 230V sinusoidal voltage at 50Hz used for supplying rural lighting applications. Combination (solar and battery) of the energy sources along with a voltage doubler forms the two input port of the DC-DC converter for solar-battery hybrid systems. To obtain a low frequency output voltage for the load modified flyback inverter structure is utilized. A control algorithm implemented to supply the load using PV and battery sources either independently or simultaneously for maintaining the constant output voltage is also presented. This work focuses on simulation studies of the same to verify the converter working using PSIM software.
