摘要:
@ An integrated circuit comprising capacitances of different capacitance values, this circuit comprising rows of basic capacitances (31. 33, 32), while the said capacitances have different numbers of basic capacitances connected in parallel between a first connection electrode (34) and an associated second connection electrode (35). Plural rows have the same number of n basic capacitances and in different ones of these rows different numbers of basic capacitances form part of the said capacitances, all the remaining basic capacitances of the relevant rows being dummy capacitances. The second capacitance electrodes (32) are connected to one or more further connection electrodes (37).

In einem isolierenden Gehäuse sind mehrere elektrisch gegeneinander isolierte Montageplatten (30, 31, 32) in ein- und derselben Ebene angeordnet, auf denen jeweils zu einer Gleichrichterbrücke gehörende Halbleiterbauelemente (33-36) elektrisch leitend befestigt sind. Damit sind ausgehend von einem einzigen Leiterrahmen (Leadframe) Halb- und Vollbrücken auf einfache Weise zu verwirklichen.
摘要:
A power rectifier (60) has a diode blank (71) sandwiched between a pair of contacts (65,67) which apply progressive compressive loads upon the diode blank as the temperature of the diode assembly increases. Preferably, the contacts are formed from dissimilar metals having different thermal expansion characteristics and are operatively coupled such that the thermal expansion differential translates into the desired compressive load characteristic.

摘要:
To provide a terminal arrangement, for a semiconductor power converter apparatus, which effectively suppresses surge voltage, caused by stray inductance of the internal wiring, with conductor bars and snubber capacitors connected between DC input terminals. Pairs of positive and negative terminals 2, 3 (2, 3) are arranged on the edge portions of the left and right sides of a rectangular upper face of the package 1, of a semiconductor apparatus for converting DC input to AC output, into which a plurality of semiconductor chips are incorporated, with the positive terminals 2, 2 and the negative terminals 3, 3 opposed facing to each other respectively. AC output terminals 4 are aligned on one of the other pair of the sides (upper side) and control terminals 5 on another side of the other side pair. Straight conductor bars 12, 12 are externally connected above the upper surface of the package 1 between the positive terminals 2, 2 and between the negative terminals 3, 3.
