Title: Lei Jin: Innovator in Motor Control Technologies
Introduction
Lei Jin is a prominent inventor based in Shanghai, China, known for his contributions to motor control technologies. With a total of 5 patents, he has made significant advancements in the field of electrical engineering, particularly in direct current (DC) bus voltage control and motor control systems.
Latest Patents
One of Lei Jin's latest patents focuses on direct current bus voltage control. This method generates a q-axis reference current from a DC voltage error, which includes a DC voltage input modified by a DC bus voltage in a closed outer loop. Additionally, it generates a d-axis reference current from the DC voltage error, ensuring that the second-order harmonic in the d-axis reference current is delayed by 90 degrees from that in the q-axis reference current. The method effectively controls the DC bus voltage of a voltage control plant to mitigate second-order harmonics in the DC bus voltage.
Another notable patent involves systems and methods for performing motor control operations that are agnostic of speed data. This system includes an inverter that converts a direct current (DC) voltage to an alternating current (AC) voltage. The control system, which is communicatively coupled to the inverter, receives torque current feedback from a motor and generates command torque and flux currents. This innovative approach allows for efficient control of the inverter based on various operating parameters.
