Title: Tshaw-Chuang Chen: Innovator in Motor Control Technology

Introduction

Tshaw-Chuang Chen is a prominent inventor based in Hsinchu County, Taiwan. He has made significant contributions to the field of motor control technology, holding a total of 8 patents. His innovative designs focus on enhancing the efficiency and reliability of electric vehicles and motor controllers.

Latest Patents

One of his latest patents is a motor controller with a reverse-bias preventing mechanism. This invention includes a pre-charging unit, a protection unit, a conversion unit, and a control unit. The pre-charging unit receives a power signal through a first electric-conduction path and converts it into a pre-charging signal based on a control signal. The protection unit determines whether to output the power signal according to its polarity. The conversion unit then converts the power signal into a work voltage, while the control unit generates the control signal based on the work voltage. Notably, the current flowing through the second electric-conduction path is smaller than that through the first.

Another significant patent is a charge-or-start system applied in electric vehicles. This system includes a charge-or-start device connected to an external power source, an on-car electric source, and a battery unit. In charge mode, the system allows either the external power source or the on-car electric source to charge the battery unit. In starting mode, the battery unit provides power to activate the on-car electric source.
