Modular bus bar and switch assembly for traction inverter |
摘要 |
An electrical power system includes an inverter having a plurality of insulated gate bipolar transistors (IGBTs) and capacitors for converting DC power to AC power and at least one power bus bar including an interconnecting bus bar and a plurality of extension bus bars. The area between the conductors of the interconnecting bus bar and the extension bus bars is minimized to reduce the inductance between the IGBTs and the capacitors. The extension bus bars are each coupled to the interconnecting bus bar and a respective one of the IGBTs and capacitors. An IGBT can be removed from the inverter without removing the interconnecting bus bar or any other IGBT. The capacitors can be positioned at ninety degree angles with respect to the interconnecting bus bar. In one embodiment, the IGBTs are additionally positioned at ninety degree angles with respect to the interconnecting bus bar. In an alternate embodiment, the IGBTs are positioned parallel with respect to the interconnecting bus bar.
