Abstract
A vehicular power converter includes switches and first and second inductive components. The first and second inductive components have substantially adjacent portions and are coupled to the plurality of switches such that when current flows from the plurality of switches and through the first and second inductive components, flux generated by the current flowing through the adjacent portions of the first and second inductive components and located between the adjacent portions is oriented in substantially opposite directions.

A vehicular power converter comprising:
- a plurality of switches;
- and
- first and second inductive components having substantially adjacent portions and being coupled to the plurality of switches such that when current flows from the plurality of switches and through the first and second inductive components, flux generated by the current flowing through the adjacent portions of the first and second inductive components and located between the adjacent portions is oriented in substantially opposite directions.
An automotive power converter comprising:
- a plurality of pairs of switches;
- a first inductor comprising a first conductive winding coupled to the plurality of pairs of switches, the first conductive winding having first and second portions;
- and
- a second inductor comprising a second conductive winding coupled to the plurality of pair of switches and the first conductive winding, the second conductive winding having first and second portions, the first and second inductors being configured such that the first portions of the first and second conductive windings are between the second portions of the first and second conductive windings and when current flows through the plurality of pairs of switches and the first and second inductors,
- flux generated by the current flowing through the first portion of the first conductive winding and located between the first portions of the first and second conductive windings is oriented in a first direction, and
- flux generated by the current flowing through the first portion of the second conductive winding and located between the first portions of the first and second conductive windings is oriented in a second direction, the second direction being substantially opposite the first direction.

An automotive drive system comprising:
- an electric motor;
- a power converter coupled to the electric motor and configured to be coupled to a first voltage source and a second voltage source, the power converter comprising a plurality of switches and first and second inductive components;
- and
- a microprocessor in operable communication with the power converter, the microprocessor being configured to activate the plurality of switches to cause current to flow through the first and second inductive components,
- wherein the first and second inductive components are configured such that the first portion of the first inductive component is between the second portion of the first inductive component and the second inductive component and when current flows from the plurality of switches and through the first and second inductive components,
- flux generated by the current flowing through the first portion of the first inductive component and located between the first portion of the first inductive component and the second inductive component is oriented in a first direction, and
- flux generated by the current flowing through the second inductive component and located between the first portion of the first inductive component and the second inductive component is oriented in a second direction, the second direction being substantially opposite the first direction.
