蓄电池及充放电技术是新能源汽车的核心技术之一，应用在车网互动中的双向DC-DC变换器日益成为新能源汽车行业的研究重点。本文设计一种新能源汽车用新型双向全桥CLLC谐振式DC-DC变换器，提出一种基于PID控制器的电压电流双闭环控制系统，形成谐振型双向全桥DC-DC变换器，以拓宽ZVS范围，降低关断损耗，实现能量的双向流动与完全的软开关化，提高能量利用率。

Battery and charge-discharge technology are one of the core technologies of new energy automobiles.Bi-directional DC-DC converter applied in vehicle network interaction is increasingly becoming the research focus of the new energy automobile industry.This paper designs a new type of two-way full-bridge CLLC resonant DC-DC converter for energy automobiles.A voltage-current double-closed-loop control system based on PID controller is proposed,which forms a resonant two-way full-bridge DC-DC converter to widen the ZVS range,reduce the power loss,realize the two-way flow of energy and complete sof...
