1. A modular bus bar and switch assembly for converting DC power to AC power in an electrical power system, the assembly comprising:

  • a plurality of electronic switching devices;

    a plurality of heat sinks, each heat sink adapted to remove heat from a respective one of the electronic switching devices;

    at least one DC link capacitor;

    an interconnecting bus bar; and

    a plurality of extension bus bars, the extension bus bars each coupling the interconnecting bus bar to a respective one of the electronic switching devices or the at least one DC link capacitor, whereineach one of the electronic switching devices and its respective heat sink are removable without removal of the interconnecting bus bar or any other of the electronic switching devices, andan area between the conductors of the interconnecting bus bar and the extension bus bars which is minimized so that an inductance between each one of the electronic switching device and the at least one DC link capacitor is low.
