变流器控制系统中开关电源PCB布局研究

Study on PCB Layout of Switching Power Supply in Converter Control System

光伏并网逆变器在光伏电站中起着决定性的作用,而控制系统就像光伏并网逆变器的大脑控制着逆变器正常稳定的运行。控制系统中开关电源的稳定性直接关系到光伏电站的稳定运行。文中通过对光伏电站现场故障原因的分析,提出开关电源的PCB布局在光伏逆变器中应用的几点要求。

Photovoltaic grid connected inverter plays a decisive role in photovoltaic power plants,and the control system is like a photovoltaic grid connected inverter which controls the normal and stable operation of inverter.The stability of the switching power supply in the control system is directly related to the stable operation of the photovoltaic power station.Through the analysis of the reasons for the field failure of the photovoltaic power station,the paper put forward some requirements for the application of the PCB layout of the switching power supply in the photovoltaic inverter.
