Latest Patents
One of his latest patents is titled "System and method of a robust startup and stop scheme for position sensorless control of an electric machine." This invention involves a system and method for controlling an electric machine via an inverter. It includes a speed estimator that estimates the rotor speed of an electric motor to determine the appropriate mode of operation. The first mode is a current-frequency control mode, while the second mode is a back electromagnetic force (BEMF) mode. The electronic data processor or controller determines the current command based on the estimated rotor speed in relation to a speed threshold.
Another notable patent is "Spread-spectrum control for an inverter for controlling an electric machine." This invention features an electronic data processor that communicates with a data storage device. The control module, stored in the data storage device, contains software instructions that dynamically change the fundamental switching frequency of control signals. This adjustment aims to reduce electromagnetic noise within a target frequency band when the fundamental switching frequency meets or exceeds a specified threshold.
