Abstract
A power module makes it possible to simplify an assembly process by disposing a compact, unified insulating substrate in a single casing, reduce overall size by selectively applying the insulating substrate according to specifications of the power module, and improve reliability by preventing a decrease in lifespan due to heat as the size of the insulating substrate is reduced. In other words, by placing the compact, unified insulating substrate in parallel in the casing, the assembly process of the insulating substrate may be facilitated, and as the size of the insulating substrate is reduced, the performance and reliability of the power module can be improved.
Claims13
A power module, comprising:
- insulating substrates, to each of which a corresponding chip is bonded;
- and
- a casing provided with mounting portions into which the insulating substrates are respectively inserted, and provided with a bus bar electrically connected to the insulating substrates inserted into the mounting portions,
- wherein the mounting portions are provided to support the insulating substrates, and
- wherein the casing is configured in plurality and combined to be stacked, and the casings are spaced apart in a stacking direction so that the respective insulating substrates of the casings do not come into contact with each other.
A power module, comprising:
- a lower casing provided with a plurality of first mounting portions into which a plurality of first insulating substrates to which chips are bonded are inserted, and provided with a first bus bar electrically connected to the first insulating substrates inserted into the first mounting portions;
- and
- an upper casing provided with a plurality of second mounting portions into which a plurality of second insulating substrates to which chips are bonded are inserted, and provided with a second bus bar electrically connected to the second insulating substrates inserted into the second mounting portions,
- wherein the lower casing and the upper casing are vertically coupled, and
- wherein the first bus bar is provided each on a first side and a second side of the lower casing, while the second bus bar is provided each on a first side and a second side of the upper casing, and the first bus bar and the second bus bar are disposed to cross each other in a vertical direction thereof.
