Patent number: 11967913Abstract: 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.Type: GrantFiled: May 12, 2022Date of Patent: April 23, 2024Assignee: Exro Technologies Inc.Inventor: Eric Hustedt

Patent number: 10483899Abstract: An electrical power system for a six-phase electric motor having a first set of three-phase windings and a second set of three-phase windings. A first pulse width modulator operates at a conversion frequency and at a first phase which converts a DC power source to an alternating current to power the motor. The first pulse width modulator is electrically connected to the first set of three-phase windings. Similarly, a second pulse width modulator also operates at the same conversion frequency and at a second phase which converts the DC power to alternating current to power the second set of three-phase windings. The first and second phases of the first and second pulse width modulators are offset between 80-100 degrees.Type: GrantFiled: June 13, 2016Date of Patent: November 19, 2019Assignee: KSR IP Holdings, LLCInventor: Eric Hustedt

Patent number: 10411632Abstract: A system for detecting and eliminating harmonic effects in the DQ plane of the non-sinusoidal back EMF voltages is provided. The system is a field oriented controller (FOC) that includes a poly-phase electric machine, proportional-integral-derivative controllers and a microcontroller. The microcontroller not only analyzes a stator current but analyzes a back electromotive force (BEMF) voltages to extract flux vectors of the EMF. These vectors have distortions as a result of the geometries and saturation effects inherent in the electrical machine. Therefore, the microcontroller corrects these defects by transmitting the BEMF vectors and the machine operating points, including the current rotational speed and current, into the algorithm, which in turn develops a command voltage in the DQ frame for the specific operating point. This command voltage is inserted into the control output of the current PI controller so to prevents the non-sinusoidal back EMF voltages from generating non-sinusoidal currents.Type: GrantFiled: February 14, 2018Date of Patent: September 10, 2019Assignee: KSR IP Holdings, LLCInventors: Eric Hustedt, Pacifique Maisha
