For the better performance and/or the high speed running for electric rolling-stocks, high accuracy power factor control with PWM power converter fed by ac power line has become popular. It is practically easy to control actual power factor itself at the input point of the power converter on the rolling-stock, however, the more important is that at substations. Although there are some technical difficulties for detecting the correct voltage phase angle on the train, caused by, for example, interference from thyristor controlled converters, suitable target value for practical power factor can be calculated under reasonable conditions. Among some kinds of control concept, the instantaneous current control referring sinusoidal waveform is the most suitable solution for the Japanese Shinkansen. The test results proved the expected power factor control performance.
