Filed: 2004-12-16
Abstract: <P>PROBLEM TO BE SOLVED: To favorably suppress a beat phenomenon due to a pulsating component included in inverter DC input voltage.  <P>SOLUTION: This drive for an electric rolling stock for controlling an AC motor from a single-phase AC power supply through a converter, smoothing capacitor, and inverter, is provided with an inverter compensation frequency generating devices 34 and a compensation frequency generating device 38. Current components on two axes (an excitation current component and a torque current component) are computed from an instantaneous current of inverter output by a current vector computing device 21. From either or both of the current components on the two axes, the pulsating components arising from rectification of the converter contained in the current components are detected. Based on the detection value, the inverter compensation frequency generating device 34 adjusts the frequency (or phase) of the AC output of the inverter so that the detection value approaches zero. Pulsating components arising from rectification of the converter, which are superposed on the direct current voltage of inverter input, are detected, and according to the pulsating components, the compensation frequency generating device 38 adjusts the frequency (or the phase) of the AC output of the inverter in such a direction that the beat phenomenon due to a pulsation in rectification is suppressed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
