Latest Patents

Jeffrey Okyere holds a patent for a "Microstepper motor control circuit PWM output coupled to H-bridge gates." This stepper motor control system includes mechanisms for stepper motor error reduction. The system utilizes first and second power switches to energize and de-energize a stepper motor coil during each cycle, effectively pulse-width modulating (PWM) the coil current. During cycles that include a zero crossing microstep, a calibrator detects the body diode effect occurring in the second power switch. This detection allows for the adjustment of a selected offset, which controls the trigger time for a comparator that compares an offset reference voltage to a motor voltage developed in response to the coil current. By progressively adjusting the selected offset over successive cycles, the system compensates for delays in the PWM control loop, thereby reducing errors caused by variations in process, voltage, and temperature.
