Electrical power system for a vehicle

A vehicle power supply system comprising:

• plural phase module assemblies each including:
• a first flat laminated busbar elongated along a first direction, the first flat laminated busbar including a first positive layer, a first negative layer, and a load layer configured to be conductively coupled with a vehicle load, the first flat laminated busbar including internal positive and negative terminal connectors for connecting the first flat laminated busbar to a second flat laminated busbar, the second flat laminated busbar including a second positive layer and a second negative layer extending in a plane that is orthogonal to the first direction of the first flat laminated busbar, the second flat laminated busbar including external positive and negative bushings configured to be conductively coupled with a vehicle power source of direct current, wherein the internal positive and negative terminal connectors are conductively coupled with the external positive and negative bushings to receive the direct current from the power source;
• one or more transistors conductively coupled with the internal positive and negative terminal connectors and configured to convert the direct current into one phase of a multi-phase alternating current of a multi-phase inverter, and to output the phase of the multi-phase alternating current to the load;
• and
• one or more capacitors conductively coupled with the internal positive and negative terminal connectors, with the external positive and negative bushings, and configured to be conductively coupled with the power source of direct current,
• wherein the phase module assemblies are conductively coupled with the power source to separately receive different portions of the direct current and to separately generate different phases of the multi-phase alternating current for the vehicle load.
