Power converter connection configuration
First Claim
1. A modular power converter comprising:
- a converter including a support including a passage for circulation of a cooling medium and a power electronic switching circuit mounted on the support and configured to convert input power to output power having desired electrical characteristics;
a housing at least partially surrounding the converter;
at least one plug-in connector coupled to the switching circuit and to the housing for establishing electrical continuity between the converter and external circuitry; and
a connection interface coupled to an exterior surface of the housing and including the at least one plug-in connector, wherein the connection interface includes connections for incoming and outgoing cooling fluid.

Abstract
EMI shielding is provided for power electronics circuits and the like via a direct-mount reference plane support and shielding structure. The thermal support may receive one or more power electronic circuits. The support may aid in removing heat from the circuits through fluid circulating through the support. The support forms a shield from both external EMI/RFI and from interference generated by operation of the power electronic circuits. Features may be provided to permit and enhance connection of the circuitry to external circuitry, such as improved terminal configurations. Modular units may be assembled that may be coupled to electronic circuitry via plug-in arrangements or through interface with a backplane or similar mounting and interconnecting structures.
