    • In a conventional electrical power conversion apparatus, a control microprocessor performs a control for eliminating or curbing a beat phenomenon, so that a control delay occurs because computing time is required in the control microprocessor. Because of the control delay, it is not possible to obtain an effect of sufficiently reducing a current ripple and torque pulsation. In addition, in an electric train in which a frequency of an AC power source is changed over while the train is running, it is required for a method of detecting a ripple component by a band-pass filter that a plurality of band-pass filters are provided and then the changeover is performed depending on the power source frequency, resulting in difficulties to take countermeasures. An electrical power conversion apparatus according to the present invention stores DC voltage values at predetermined sampling time-points going back from the latest, and predicts a DC voltage estimate value for a predetermined elapse time from the latest sampling time-point using the stored DC voltage values, whereby using the predicted DC voltage estimate value, an amplitude and/or a frequency of AC power that an inverter outputs is controlled so as to curb variation of the AC power that the inverter outputs, due to a ripple caused on the DC side of the inverter.

    • In a conventional power converting device, control for eliminating or suppressing a beat phenomenon is performed by a control microcomputer. Since computation time is required by the control microcomputer, control delay is generated. Because of the control delay, the effect of fully reducing the pulses of current and torque cannot be obtained. Further, a method for detecting a pulse component using a band-pass filter does not cope with a train in which the frequency of an alternating-current power is switched while the train is running, since a plurality of band-pass filters are required to be provided and switched according to the frequency of the power. A power converting device according to the present invention stores a direct-current voltage value at the predetermined times of sampling from the latest, estimates a direct-current voltage estimation value after the passage of predetermined time from the latest sampling using the stored direct-current voltage value, and controls the amplitude or the frequency of alternating-current power outputted from an inverter using the estimated direct-current voltage estimation value so that the variation of the alternating-current power outputted from the inverter caused by a pulse in the direct current side of the inverter is suppressed.
    • 在传统的电力转换装置中,通过控制微计算机执行用于消除或抑制拍频现象的控制。 由于控制微计算机需要计算时间,所以产生控制延迟。 由于控制延迟,不能充分降低电流和转矩脉冲的影响。 此外,使用带通滤波器检测脉冲成分的方法不能应对在列车运行时切换交流电力的频率的列车,因为需要多个带通滤波器 根据电源的频率提供和切换。 根据本发明的电力转换装置在最新的采样的预定时间存储直流电压值,在使用所存储的直流电流的最新采样之后的预定时间过去之后估计直流电压估计值 电压值,并且使用所估计的直流电压估计值来控制从逆变器输出的交流电力的幅度或频率,使得由直流电中的脉冲引起的逆变器输出的交流电力的变化 逆变器侧被抑制。
