Electric power conversion apparatus |
摘要 |
An electric power conversion apparatus includes a noise reduction device for reducing the common mode noise and the normal mode noise caused by on/off of the switching devices of an electric power conversion apparatus for driving an AC motor. Since the noise-compensation-current supply circuit of the noise reduction device uses devices with a lower breakdown voltage, the operating speed of the noise-compensation-current supply circuit is higher than the operating speed of the conventional noise-compensation-current supply circuit which uses devices with a higher breakdown voltage equivalent to the DC voltage of the electric power conversion apparatus.
