Figure 6From: Multirate PWM balance method for the efficient field-circuit coupled simulation of power convertersCoefficients \(w_{1,k}\) for the inductor current calculated by solving (13) with \(N_{\mathrm {p},\mathrm {pwmbal}}=4\). (top) real part. The coefficients \(w_{1,1}, \dots , w _{1,4}\) are approximately the same therefore they are hard to distinguish visually. (bottom) imaginary partBack to article page
