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.
