摘要
针对电梯门机用交流电机变频器市场上变频器价格昂贵,设计了一种高效、低成本、功能完备的小型变频器。主要介绍了变频器的功能与结构,利用SPWM专用芯片,采用V/f控制方式,用软件程序实现对SPWM波形的优化和功能控制。试验结果表明系统的性能指标良好,有一定推广应用价值。
Designed highed-effeciency, low cost and full function small frequency converters, because the universal frequency converters is expensive in the market for door machine of elevator. Mainly researched the function and structure of the converters. The system used the special IC and adopts V/f control strategy. The software is utilized to realize the optimization of the SPWM waveform and function control.
