摘要
本文介绍了一种船用三相异步风机启动器的设计,基于成熟的两电平三相逆变桥设计方案,主开关器件为IGBT模块,采用基于恒压频比的控制方式,同时,考虑到输入直流母线电压的波动以及输出三相交流电压谐波对负载振动加速度的影响,增加对直流母线电压和交流输出端的滤波环节,取得了良好的应用效果。
A design scheme of Marine asynchronous motor starter is introduced.The design is based on the principle of three-phase inverter and IGBT modules and the control model of constant ratio of voltage to frequency meanwhile,with filtering circuits adopted in the input and output links.The verification tests shows that the scheme is feasible and achieved good results.
