Abstract
An EMC filter device for power electronics of an electric machine includes an electric conductor structure, a capacitor coupled to the conductor structure, and an inductor that cooperates with the conductor structure. The conductor structure has at least two separate conducting layers that are insulated from one another.
Claims15
An EMC filter device for power electronics of an electric machine, comprising:
- an electrical conductor structure, a capacitor coupled to the electrical conductor structure and an inductor interacting with the electrical conductor structure, the electrical conductor structure having two separate conducting layers insulated from one another, wherein the inductor has a ring-shaped core, and the electrical conductor structure is inserted through the core, wherein the electrical conductor structure is configured to mount to a housing of an inverter unit on opposite axial sides of the core, and wherein the electrical conductor structure is configured to lie flat on a housing of an inverter unit such that the core can be least partially received in the housing of the inverter unit.
A power electronics module for an electric machine, comprising:
- a capacitor arrangement;
- and an EMC filter device electrically connected to the capacitor arrangement, the EMC filter device including:
- an electrical conductor structure, a capacitor coupled to the electrical conductor structure and an inductor interacting with the electrical conductor structure, the electrical conductor structure having two separate conducting layers insulated from one another, wherein the inductor has a core, and the electrical conductor structure is inserted through the core, wherein the electrical conductor structure is mounted to a region fixed to a housing of an inverter unit on opposite axial sides of the core, and wherein the core is at least partially in the inverter housing.
