Abstract
A system is shown for cooling components of an inverter. In one example, an inverter comprises a first compartment including a direct current (DC) link capacitor that is electrically coupled to a discharge resistor; and a thermal pad in contact with the DC link capacitor; a cooling system configured to circulate coolant through a housing adjacent to the thermal pad; and a noise filtering ferrite element coupled to a DC bus bar. A cooling plate may be further included between the DC link capacitor and the thermal pad and during a during a first condition when the inverter is operating, heat is transferred from the DC link capacitor to the cooling system; and during a second condition when the inverter is not operating, heat is reduced in the DC link capacitor by discharging electricity stored in the DC link capacitor via the discharge resistor.
