Study on Current-fed Dual-active-bridge DC-DC Converter Based on Coupling Filter Inductance
摘要
Abstract
In an energy storage system,the current-fed dual-active-bridge converter has a large current stress and the corresponding soft-switching range is limited,which limits the converter's efficiency and power density.To solve these problems,combined with the coupled inductor technology,a current-fed dual-active-bridge converter with a low current ripple on the energy storage side and a wide soft-switching range is proposed.Two current-fed full bridges are connected in parallel on the energy storage side,thus effectively reducing the current stress of switches therein.By adjusting the phase shift angle between the two parallel full bridges on the energy storage side,the current ripple is reduced.By reasonably designing the coupling filter inductance,the obtained mutual inductance current is large enough to satisfy the soft-switching conditions for switches.The working principle and steady-state analysis of the converter were given in detail,and a 400 W experimental prototype was designed to verify the superiority and feasibility of the proposed converter.关键词
