Movement and control system

运动与控制系统

Abstract

The invention provides a movement and control system which comprises a rectifier, a flat wave circuit, a main power stage, a standby power stage and a controller. The rectifier is used for converting alternating currents into direct currents; the flat wave circuit is used for smoothing waveforms of the direct currents output by the rectifier; the main power stage and the standby power stage are connected between the flat wave circuit and a motor in parallel; in a normal working mode, the controller drives the main power stage to convert the direct currents from the flat wave circuit into alternating-current voltages supplied to the motor, and when the situation that the main power stage breaks down is confirmed, the controller drives the standby power stage to convert the direct currents from the flat wave circuit into alternating-current voltages supplied to the motor.
本发明提供一种运动与控制系统,包括:整流器,用于将交流电变换为直流电;平波电路,用于对整流器输出的直流电的波形进行平滑处理;主功率级和备用功率级,并联连接在平波电路与电机之间;以及控制器,在正常工作模式下,驱动主功率级将来自平波电路的直流电压变换为提供给电机的交流电压,当确定主功率级发生故障时,驱动备用功率级将来自平波电路的直流电压变换为提供给电机的交流电压。
