Figure 1

Simplified circuit of the buck converter in continuous conduction mode with \(C=10~\text{$\mu $F}\) and \(R=30~\varOmega \). The field model of the pot inductor (axisymmetric around z-axis) is designed to have an inductance of \(L=65~\text{mH}\) and a series resistance of \(R_{\mathrm {L}}=800~\text{m$\varOmega $}\) at DC. The figure shows the equipotential lines of the magnetic vector potential
