Title: Innovations of Hong-Sheng Ouyang

Introduction

Hong-Sheng Ouyang is a notable inventor based in Shenzhen, China. He has made significant contributions to the field of battery charging technology, holding a total of five patents. His work focuses on improving the efficiency and effectiveness of battery charging circuits.

Latest Patents

One of his latest patents is a "Battery charging circuit with trickle charging mode." This invention provides a battery charging control circuit that charges batteries in phases. In the first charging phase, the circuit charges the batteries with a large current, while in the second phase, it charges them with a much smaller current. The circuit includes a current detection mechanism that detects the charge current and provides a detection voltage proportional to it. An amplifier circuit amplifies this detection voltage, and a comparison module compares it with a reference voltage. If the amplified detection voltage is lower than the reference voltage, the comparison module outputs a switch signal to a control module. This control module then manages the charging module to charge the battery in trickle mode upon receiving the switch signal.

Another significant patent is the "Battery charging control circuit." This circuit includes a constant-current charging unit and a trickle charging unit. It also features a branch switch, a control unit, and a detection unit. The branch switch connects the power source to the rechargeable battery, enabling or disabling the constant-current charging unit. The control unit manages the branch switch, while the detection unit monitors the state of the rechargeable battery. If the detection unit identifies that the battery state corresponds to a predetermined condition, the control unit disables the constant-current charging unit and activates the trickle charging unit.
