Abstract
The invention provides a bridge assembly for a three-phase motor. The assembly includes a first subassembly having a first terminal plate, a second subassembly having a second terminal plate, a third subassembly having a third terminal plate and a fourth subassembly having a bus terminal plate. Each of the terminal plates is electrically isolated from the other terminal plates, and at least one of the first, second, third and bus terminal plates acts as a heat sink. The assembly further includes first, second, third, fourth, fifth and sixth switching devices interconnected to at least one of the terminal plates. Each switching device has a heat generating surface in thermal communication with one of the first, second, third and bus terminal plates. The assembly further includes a fifth subassembly interconnected with the first, second, third, and fourth subassemblies.
