Title: Jiun-Wei Tseng: Innovator in Power Solutions

Introduction

Jiun-Wei Tseng is a notable inventor based in Changhua County, Taiwan. He has made significant contributions to the field of power solutions, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of power adaptors and backlight modules.

Latest Patents

One of his latest patents is a power adaptor with a power-saving mechanism. This innovative adaptor includes an inverter, a feedback circuit, a detecting unit, and an adjusting unit. The inverter is designed to convert an input voltage into an output voltage based on a power conversion ratio, which can be adjusted according to a feedback voltage. The feedback circuit provides this feedback voltage by voltage-dividing the output voltage according to a specific ratio. Additionally, the detecting unit monitors the load at the output end of the power adaptor, while the adjusting unit modifies the specific ratio in response to variations in the load.

Another significant patent by Tseng is a backlight module with dynamic open-lamp protection and a related driving method. This invention aims to provide open-lamp protection for a backlight module by generating a pseudo open-lamp voltage based on the current flowing through a light source. When the backlight module receives a mode signal for a high contrast mode, a compensation voltage is added to the pseudo open-lamp voltage to create a reference voltage. If this reference voltage exceeds a feedback voltage from the light source's input node, a driving voltage is then outputted to the light source.
