摘要
双向DC/DC变换器是电力储能系统的重要组成部分,针对传统单相双向DC/DC变换器储能电感过大,变换器功率较低的缺点,文中提出了一种三相交错并联双向DC/DC变换器的拓扑结构。在此基础上分析了其工作原理及控制策略,并进行了仿真验证。仿真结果表明,三相交错并联双向DC/DC变换器应用于电力储能系统能获得较好的电压、电流波形,有效降低电感电流,提升系统的功率等级,为电网及储能系统的安全稳定运行提供了保障。
The bi-directional DC/DC converter is an important part of the power.energy storage system. Due to the using of single-phase circuit structure, traditional bi-directional DC/DC converter＇s energy storage inductance is too large, the ascension of the converter power has limited. In this paper, a three-phase interleaved bi-directional DC/DC converter topology is proposed, and its working principle and control strategy are analyzed, and the simula- tion results are also presented. The simulation results show that the three-phase interleaved bi-directional DC/ DC converter used in electric power energy storage system can achieve better voltage and current waveforms, effectively reduce the inductance current, enhance the power level of electric system, provides a guarantee for the safe and sta- ble operation of the power grid and energy storage system .
