要約(英語): To produce DC current by using a multiphase reversible chopper, smoothing reactors are needed. When the smoothing reactors are employed, the chopper devise becomes large and heavy if electromagnetic interference is avoided.The reduction in the ripple current by electromagnetic coupling contributes to making the chopper device smaller and lighter. We deduced the relationships among the amplitude of ripple current, duty factor, electromagnetic coupling coefficient. To determine the loss and gain, we introduced the ratio of the amplitude of ripple current in each phase and in total combined of multiphase chopper system to that of the ripple current in one-phase chopper, Aph, Asum respectively. This value indicates the reduction in not only the amplitude of ripple current but also self-inductance. The minimum value of the abovementioned ratio obtained analytically is accurately determined. We led the minimum values and obtained the range which implement to reduce the amplitude of ripple current both each phase and total combined. Finally, we applied an optimal electromagnetic coupling coefficient to the design of onboard reactors of electric railway vehicles.
