一种新型的双向DC/DC变换器分析

本文提出了一种新颖的蓄电池充放电系统。选取全桥电路作为主电路拓扑。全桥变换拓扑优点较多,是高质量、大功率变换的主流拓扑。该装置的控制系统采用电压外环电流内环的双闭环控制方式,内环采用峰值电流控制,通过对内环的降阶处理,简化了系统调节器的设计。采用PWM控制方式实现双向DC/DC变换。

Analysis of a new bi-directional DC/DC converter

This paper present a Novel Battery Charger/Discharger system. Full-bridge circuit is selected as the main circuit topology in this paper. Due to many of its advantages, it has been the mainstream topology adopted in large high performance power converters. Current and voltage double closed-loop control strategy is applied to the converter, in which current loop is inside and voltage loop is outside. Peak current control strategy is used in the current loop. The current loop can be considered as a proportion...
