摘要
采用常规技术的充电桩计量检定系统效率低下,交流电供电方式,纹波输出噪音大,检定精度不灵敏,因而设计了基于瞬时有功同步原理的直流充电桩效率检测装置,提高了交流功率和直流功率在信号测量中的同步应用能力。通过试验,本研究纹波输出低、误差低。
In the conventional technology,the efficiency of charging pile measurement and verification system is low.AC power supply mode is usually adopted,and is with large ripple output noise and insensitive verification accuracy.In this study,a DC charging pile efficiency detection device based on instantaneous active power synchronization principle is designed to improve the synchronous application ability of AC power and DC power in signal measurement.Through the experiment,the ripple output of this study is low and the error is low.
