Three phase power bridge assembly

A switching assembly for an electric vehicle propulsion system, comprising:

• a capacitor having a first terminal and a second terminal;
• an electronic switch having a first input terminal and a second input terminal;
• a bus bar having a first electrically conducting section and a second electrically conducting section, the bus bar being sandwiched between the capacitor and the switch;
• first electrically conducting connecting means for connecting the first terminal of the capacitor, the first terminal of the switch, and the first section of the bus bar to one another;
• and
• second electrically conducting connecting means for connecting the second terminal of the capacitor, the second terminal of the switch, and the second section of the bus bar to one another, said electronic switch comprising at least one insulated gate bipolar transistor.

A switching assembly for an electric vehicle propulsion system for converting input direct current to output alternating current for driving an electric vehicle propulsion system, comprising:

• a capacitor having a first terminal and a second terminal;
• an electronic switch comprising:
• first and second insulated gate bipolar transistors each having a gate, a collector, and an emitter, the emitter of the first transistor being connected to the collector of the second transistor;
• a first input terminal connected to the collector of the first transistor;
• a second input terminal connected to the emitter of the second transistor;
• and an output terminal connected to the emitter of the first transistor and the collector of the second transistor;
• a bus bar having an upper plate, a lower plate, and an insulator sandwiched between the upper and lower plates, the bus bar being sandwiched between the capacitor and the switch;
• first electrically conducting connecting means for electrically and mechanically connecting the first terminal of the capacitor, the first input terminal of the switch, and the upper plate of the bus bar to one another;
• and
• second electrically conducting connecting means for electrically and mechanically connecting the second terminal of the capacitor, the second input terminal of the switch, and the lower plate of the bus bar to one another.
