摘要：
Variable voltage variable frequency (VVVF) inverter systems have been utilized for propulsion of electric railway cars, and it has been essential to reduce electromagnetic noise caused by those inverter systems. One of the EMI issues is AM radio noise which should be reduced in order to guarantee the service for railway passengers. However, detailed countermeasures of noise reduction and circuit simulation methods to estimate the noise current focusing on the AM radio frequency band have not been reported yet. This paper focuses on AM radio noise and its current, and suggests a detailed noise reduction method targeting a VVVF inverter on an electric railway car. The simulated and measured currents are compared, and the effectiveness of the simulation model is verified under the conditions of with and without the countermeasure.
