Laminated bus bars: design, fabrication, and testing considerations

Laminated bus bars address two power-related design challenges: they significantly reduce voltage drop due to IR loss in high-current power-distribution systems, and their very low stray inductance minimizes a possible cause of instability and output oscillation in switching power supplies.  Depending on size and thickness, laminated bus bars can support voltages and currents ranging from low, single-digit values up to hundreds of volts and amps and even higher. These bus bars are a clean, clear, and direct mechanical solution to a problem defined by electrical engineering realities, and can even provide some relief to heat-dissipation issues.
