Abstract

In this paper, a design of interleaved flyback converter with H6 inverter topology is proposed. Flyback converter is one among the DC-DC converter with high frequency which is used or low power applications. Because of high frequency operation switching losses and stresses are more. To reduce stresses and losses across the switch of interleaved flyback converter is proposed. In the grid tied inverter system leakage current is one of the disadvantages and to avoid this H6 type inverter is used.With this advantage of H6 inverter andflyback converter this paper is mainly focused on stresses across switches and eliminating leakage current, harmonic reduction. Further the fast switching is proposed within converter in order to deliver maximum power transfer delivered to load through grid. To validate the overall performance the proposed converter modeled in MATLAN-SIMULINK and prototype developed using DSP DSP TMS320F28377S and connected to grid connected load.

光伏用H6型逆变器交错反激变换器的快速零电压开关设计

本文提出了一种基于H6逆变器拓扑结构的交错反激变换器设计。反激变换器是高频DC-DC变换器中的一种，应用于低功耗场合。由于工作频率高，开关损耗和应力较大。为了减小交错反激变换器开关处的应力和损耗，提出了一种方法。在并网逆变器系统中漏电流是缺点之一，为了避免这一点，采用了H6型逆变器。利用H6逆变器和反激变换器的这一优点，本文主要研究开关间应力的消除、漏电流的消除、谐波的降低。在此基础上，提出了变流器内部的快速开关，以实现通过电网向负载的最大功率传输。为了验证该变换器在MATLAN-SIMULINK中建模的整体性能，并利用DSP TMS320F28377S开发了样机，并与并网负载连接。

期刊介绍： International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
