Abstract: An article for a power inverter, includes a multilayer printed circuit board having a first and second electrically conductive wiring layer and at least a first dielectric layer interposed between the first and second electrically conductive wiring layers. Each conductive wiring layer includes a common input and output line, the common input and output lines at least partially overlapping one another in a projection along a thickness of the multilayer printed circuit board. A set of input mounting pads is carried by the first common input line and a set of input mounting pads is carried by the second common input line, the input mounting pads of the second set of input mounting pads are interleaved with the input mounting pads of the first set of input mounting pads along a first axis. The article further includes a set output mounting pads carried by the common output line.

Abstract: Disclosed is a series mode modulation configuration and a parallel voltage equivalent modulation configuration. In the series mode modulation configuration a unipolar modulation is utilized. Unipolar modulation utilizes a zero vector and produces a voltage across the load with a frequency factor of 2×. In the parallel voltage equivalent mode modulation configuration there are two H bridges driving two coils with identical current. The H bridges can advantageously be operated out of phase with one another (e.g., 180 out of phase with one another to interleave the currents to further reduce ripple current stress.

Abstract: A battery control system includes a plurality of battery cells that are separately controllable as units of individual cells or groups of cells. Each controllable unit may be switchably activated or deactivated in the overall battery circuit, and one or more conditions of each controllable unit may be individually measured. Various techniques are disclosed for operating the battery control system to optimize or improve system performance and longevity.
