| 摘 要： | 在大容量特别是大电流的电机传动系统中,逆变器需要采用多个逆变模块并联的结构.文中对2个电压源逆变器通过均流电抗器并联带三相电机负载的传动系统进行了分析.围绕并联技术的均流问题,借鉴电源模块的并联控制,提出了同步坐标系下转速电流双闭环的主从控制策略,通过共用转速调节器实现负载均分,并对电路中的零序电流进行控制.仿真和实验结果表明,该控制策略在保证电机动态性能较好的基础上实现了逆变器均分负载电流.

| Abstract: | Parallel connection of inverters or converters is one useful method for solving the high power requirements.The structure of two voltage inverters are paralleled by intermodule reactors with a standard three-phase machine is analysised in the paper.To the current-sharing problem,the paper presents the master-slave method of double close-loop.Through the same speed regulator,the current-sharing is achieved.The control of the zero-seaquece current is also analyzed.The simulation and experimental results confi... |
