Latest Patents

One of Korol's latest patents is focused on three-phase motor current measurement. This invention involves methods and apparatus for controlling a three-phase electric motor by determining the duration of current measurement windows within a first pulse width modulation (PWM) period. The system measures motor current using a single shunt coupled to the motor, with the ability to adjust the duration of the current measurement windows to meet a minimum time requirement. Additionally, the next PWM period can include compensation for any time delta value, enhancing the efficiency of the motor control.

Another notable patent by Korol is a motor controller that features back electromotive force (BEMF) compensation for noise and vibration reduction. This invention addresses the challenges posed by non-sinusoidal BEMF signals in electrical motors. It utilizes amplitudes, phases, and orders of BEMF harmonic components to generate corrective components for the d-q coordinate system of the motor. This innovative approach significantly improves the performance and reliability of electric motors.
