摘要： An electrical cable for use in high-frequency, high power applications, such as with an inductive charging system used to charge batteries of an electric vehicle. The cable has multiple twisted-pairs of separately insulated stranded wire arranged in a pseudo-Litz wire architecture that surround a coaxial cable. The coaxial cable carries bidirectional RF communication signals between a power source of the charging system and the vehicle. The cable has an outer EMI shield that includes a metalized mylar layer surrounded by a high coverage tinned-copper braid layer. The multiple twisted-pairs of wires and coaxial cable are embedded in a polytetrafluoroethylene filler material that surrounds them inside the outer EMI shield. An outer silicone cover is disposed around the outside of the cable. The cable efficiently transfers power at high-frequency AC power, between 100 KHz to 400 KHz at high-voltage levels, on the order of from 230 V to 430 V. The cable carries bidirectional RF communication signals using a 91.5 MHz carrier frequency. The cable is designed for use in an outdoor operating environment while maintaining its flexibility. The cable also has sufficient shielding to maintain EMI compatibility with other consumer products.

摘要： The present invention includes a method for thermal management in a voltage source inverter. The method includes sensing a low output frequency condition, determining a zero vector modulation responsive to the sensed low output frequency condition, and applying the determined zero vector modulation to reduce thermal stress in the voltage source inverter. The step of determining the zero vector modulation responsive to the sensed low output frequency condition includes mapping an output voltage requirement to a space vector structure and determining state switching space vectors based on the mapped output voltage requirement. The step of determining the state switching space vector includes determining active state switching space vectors associated with the state switching space vectors, determining duty cycles for the active state switching space vectors based on the active state switching space vectors, and determining a duty cycle for at least one zero state switching space vector based on the determined duty cycles of the active state switching space vectors and a switching period.

摘要： A power electronics chassis (10) for electric vehicles and other applications that use liquid coolant to cool power electronic devices (20) contained within the chassis. The chassis (10) includes an electrically conductive housing (12) and an electrically non-conductive manifold (16) that permits coolant flow into and out of the housing. The housing (12) has at least one wall (34) that includes an outer surface (42) and a pair of recessed apertures (36,72), each of which provide access to an interior region (38) of the housing (12) via a passageway (40,74). The manifold (16) has an inlet (26) and an outlet (28), each of which has a connecting tube (54,80) that extends through one of the passageways (40,74). Each passageway (40,74) is defined by an axial wall (44,78) of the housing (12) that extends towards the interior region (38) from the outer surface (42) to its respective aperture. The apertures (36,72) are each formed by an annular wall (50,76) that extends radially inward from its associated axial wall (44,78) at the interior end of its passageway. The outer diameter of the connecting tubes (54,80) are equal to the diameter of their respective apertures (36,72). Thus, each tube (54,80) is in contact with its aperture (36,72) and is separated from its adjacent axial wall (44,78) by an annular gap (70). This configuration provides electrical isolation of the coolant from the chassis (10) in a manner that significantly reduces the radiated emissions at the apertures (36,72).

摘要： A power electronics chassis (10) and liquid-cooled heat sink mounting assembly for electric vehicles and other applications that use liquid coolant to cool power electronic devices (20) contained within an electrically conductive housing (12). The power electronics chassis (10) includes an inverter (18) containing power switching devices (20) that are heat sunk using the liquid-cooled mounting assembly. The mounting assembly includes a heat exchanger (22) and a plastic, electrically non-conductive coolant manifold (16) that has an inlet (26) and outlet (28) for passage of liquid coolant into and out of the electronics housing (12). The power switching devices (20) are attached to a mounting surface (40) of the heat exchanger (22) and are thermally coupled to the coolant within the heat exchanger (22) via the mounting surface (40). The inlet (26) and outlet (28) of the plastic coolant manifold (16) are connected to the heat exchanger (22) by conduits (30,32) to thereby permit circulation of liquid coolant into the chassis housing (12), through the heat exchanger (22), and back out of the chassis housing (12) while maintaining electrical isolation between the liquid coolant and chassis housing (12). This configuration significantly reduces the radiated EMI by significantly reducing the parasitic capacitance between the switching devices (20) and chassis housing (12).
