Title: Jong-Ruey Yang and Multiphase Motor Control
Introduction
Jong-Ruey Yang is an inventor associated with Taipei, Taiwan, and Richtek Technology Corporation. His patent work addresses multiphase motor control, particularly the management of electrical energy during motor braking.
Latest Patents
Yang is named on 1 patent: “Multiphase Motor Driving Circuit and Multiphase Motor Driving Method.” The invention describes a power-stage circuit and a control circuit that operate in two braking sub-modes. When the holding voltage falls below a first threshold, pulse-width modulation (PWM) switches convert the motor’s back electromotive force (EMF) into a holding voltage that powers the control circuit. When the holding voltage exceeds a second threshold, PWM control keeps selected switches continuously conductive, consuming the motor’s back EMF and reducing its speed.
Career Highlights
Yang’s listed patent connects his work with Richtek Technology Corporation and focuses on motor-driving circuitry. Its two-mode braking approach is designed to support the control circuit at low holding voltage and dissipate back EMF when the voltage is higher.
Collaborations
I-Chi Lin and Hao-Che Ma are identified as Yang’s coworkers. The available information does not specify their roles in the patent or whether they collaborated with him on this invention.
Conclusion
Jong-Ruey Yang’s patent presents a two-stage method for managing back EMF during multiphase motor braking, reflecting his work in motor-control technology.
