Abstract:
A power circuit module, comprising:a planar device-on-membrane structure comprising at least one power device attached to a planar membrane, the membrane having metalized vias formed therein and the at least one power device being connected to power and control circuits through the metalized vias, the circuits being formed by metalizing the membrane and patterning prior to attachment of the power device to the planar membrane, the device-on-membrane structure having an upper portion on which the devices are attached and having a lower membrane portion; at least one electrically-insulating thermal base sub-assembly attached to the device-on-membrane structure, each thermal base sub-assembly comprising metalized base plates, the thickness of the metalization being variable so as to accommodate different types of power devices having variations in thickness; and a sealed shell structure having a first coolant enclosure embedded in a second coolant enclosure, the coolant enclosures having cavities formed therein for containing cooling media and further comprising openings for power and control feedthroughs.
