Suppression scheme on start voltage overshoot of energy router based on self-adaptive pulse width adjustment

针对两相交错式能量路由器在启动时出现的电流浪涌及电压过冲现象,提出自适应脉宽调整启动方案,使能量路由器在启动瞬间输出电压和电流的过冲得以有效抑制,并进行仿真及试验验证,结果表明该方案可以有效保证能量路由器输出电压平稳快速上升,确保接入能量路由器的微网系统维持稳定工作,可在设备实践层面为构建即插即用、开放互联的能源互联网生态提供参考。

According to the current surge and the voltage overshoot which happen at the start of two-phase staggered energy router,a start scheme based on self-adaptive pulse width adjustment is proposed,which can effectively suppress the overshoot of output voltage and current at the start of the energy router.The simulation and experimental verification are conducted.The results show that this method can effectively ensure the output voltage of energy router rise steadily and quickly,and guarantee that the micro-grid system accessing the energy router maintains stable operation.It can provide a reference for the construction of plug and play,open and interconnected energy internet ecosystem at the practical level of the device.
