The field-circuit coupled simulation of switch-mode power converters with\nconventional time discretization is computationally expensive since very small\ntime steps are needed to appropriately account for steep transients occurring\ninside the converter, not only for the degrees of freedom (DOFs) in the\ncircuit, but also for the large number of DOFs in the field model part. An\nefficient simulation technique for converters with idealized switches is\nobtained using multirate partial differential equations, which allow for a\nnatural separation into components of different time scales. This paper\nintroduces a set of new PWM eigenfunctions which decouple the systems of\nequations and thus yield an efficient simulation of the field-circuit coupled\nproblem. The resulting method is called the multirate PWM balance method.\n
