Title: Vishnu Kumar: Innovator in Motor Control Technologies
Introduction
Vishnu Kumar is a prominent inventor based in Singapore, known for his contributions to motor control technologies. With a total of 6 patents, he has made significant advancements in the field, particularly in the areas of chip initialization and disk drive systems.
Latest Patents
One of his latest patents is titled "Fast startup supply for chip initialization." This invention involves a motor driver that includes a first power supply, a second power supply, a multiplexer, and an output power module. The first power supply provides a first power signal after a first period, while the second power supply provides a second power signal after a longer second period. The multiplexer initially selects the first power signal and later switches to the second power signal, allowing the output power module to control a motor effectively.
Another notable patent is "System and process for utilizing back electromotive force in disk drives." This circuit system utilizes back electromotive force (BEMF) voltage to assist in the safe power down of devices, such as the read/write head in low factor disk drives. The BEMF voltage from a motor device helps minimize the on-resistance of switches while delivering current to another device, enhancing the efficiency of the system.
