Current sharing AC Bus Bar
First Claim
1. An AC bus assembly comprising:
- a plurality of substantially similar AC current sources connected in a plane and each having contact pads formed thereon;
a bus bar interconnecting at least one of said current sources to a peripheral device;
said bus bar comprising a plurality of elongated flat plates having a width substantially greater than its thickness and laminated to one another.

Abstract
A hybrid vehicle includes a power unit communicating power between a turbine alternator, flywheel and traction motor. The power unit stores DC power in capacitors and places the power on DC bus for use in driving the induction machines. Power transistors receive the DC power from the DC bus and are pulse width modulated to output a synthesized AC wave form at their output. An Ac bus assembly comprises the power transistor modules connected in a plane and each having contact pads formed thereon for providing AC current sources. A bus bar interconnects at least one of the current sources to a peripheral device. The bus bar comprises a plurality of elongated flat plates having a width substantially greater than its thickness and laminated to one another.

8. An AC bus assembly comprising:
-
at least three substantially similar AC current sources connected in a plane and each having contact pads formed thereon; a first plate having three connecting apertures equally spaced in said plate and connected to three of said current sources, and including two intermediate apertures formed symmetrically between said connecting apertures; a second plate stacked on said first plate and including a pair of symmetrical located receiving apertures aligned with said intermediate apertures and an output aperture formed symmetrically between said receiving apertures for providing an AC signal, said plates insulated from one another except at said receiving apertures.
