(top) Reference solution calculated using conventional adaptive time discretization compared to the solution obtained by the MPDE approach with \(N_{\mathrm {p},\mathrm {pwmbal}}=4\) PWM eigenfunctions. The relative \({\mathrm {L}^{2}}\) error of the current through the inductor similar to (27) is approximately \(3 \times 10^{-5}\). (bottom) Joule losses in the core material due to eddy currents
