| description | The invention relates to an adjustment of a PWM frequency in a power converter in accordance with the input voltage of the power converter. By means of the adjustment of the PWM frequency in the powerconverter in accordance with the input voltage, a ripple on the input side of the power converter can be varied. In particular, it is possible, in the case of high input voltages, to minimize the ripple by adjusting the PWM frequency and thus to reduce the sum of the input voltage and the ripple.
本发明涉及根据变流器的输入电压对在该变流器中的PWM频率的适配。在这种情况下，通过根据输入电压来使在该变流器中的PWM频率适配，可以使在该变流器的输入侧的纹波发生变化。在此，在输入电压高时尤其可能的是：通过使PWM频率适配来将纹波减小到最低限度并且因此减小输入电压与纹波之和。 |
