Abstract

An optimisation approach aimed at boosting the efficiency of an input parallel output parallel (IPOP) converter under light load conditions is proposed in this paper, which is constructed using two phase-shift full-bridge (PSFB) modules. The study begins by detailing the loss characteristics of the PSFB module across various load scenarios and examines how soft switching influences the overall efficiency of the converter. Following this, a numerical analysis is conducted to refine the power distribution strategy among the modules when operating under light loads, thereby maximizing efficiency. To demonstrate the practical application of this optimisation strategy, a 15 kW prototype is developed and tested.

并联移相全桥模块的效率优化策略

本文提出了一种优化方法，旨在提高输入并联输出并联（IPOP）转换器在轻负载条件下的效率，该方法使用两个相移全桥（PSFB）模块构建。该研究首先详细介绍了PSFB模块在各种负载情况下的损耗特性，并检查了软开关如何影响转换器的整体效率。在此基础上，通过数值分析细化各模块在轻负荷下的功率分配策略，实现效率最大化。为了演示该优化策略的实际应用，开发并测试了一个15千瓦的原型机。
