Enhanced Inductance and Winding Loss Model for Coupled Inductors

An enhanced model for coupled inductors with significant fringing effect is developed in the form of equivalent circuit. The equivalent circuit is derived from a physical model that captures the flux paths through a leakage inductor and two mutual inductors on the primary and secondary side. A mutual winding resistor is added in parallel with the mutual inductor to model the winding loss affected by the fringing flux that penetrates the winding. The equivalent circuit is verified by finite-element simulation (FES) and successfully predicts the open-circuit winding loss and winding loss variation with phase-shift impact.

Low inductance bus assembly and power converter apparatus including the same

An apparatus, such as a power converter, includes first, second and third core bus plates arranged in parallel. The apparatus also includes a first bus extension plate joined to the first core bus plate and extending therefrom at a first angle and a second bus extension plate joined to the second core bus plate and extending therefrom at a second angle. The apparatus further includes a third bus extension plated joined with the third core bus plate and disposed parallel to the first bus extension plate and a fourth bus extension plate joined with the third core bus plate and disposed parallel to the second bus extension plate.
