Title: Innovations by Hongbo Zhang

Introduction

Hongbo Zhang is a notable inventor based in Xi'an, China. He has made significant contributions to the field of power supply technology, holding two patents that showcase his innovative approach to electrical engineering.

Latest Patents

One of his latest patents is a feedback device for a power supply. This invention includes a main feedback module, an auxiliary feedback module, and a feedback control module. The main feedback module samples a voltage on the main output branch of the power supply and outputs a main feedback voltage to the feedback control module. The auxiliary feedback module reduces the main feedback voltage when the voltage on an auxiliary output branch drops. The feedback control module then controls the power supply to increase its power output when the main feedback voltage decreases, ensuring that the voltage on the auxiliary output branch is restored to normal. This device simplifies the circuit, effectively solving voltage sag problems while maintaining power density and cost efficiency.

Another significant patent by Zhang is a power output discharge circuit. This circuit includes an output filter module that receives and filters an input voltage, outputting the filtered voltage to a load. It also features an output charge module that charges the output filter module when a power source module is plugged into a system cabinet. Additionally, the output discharge module works in conjunction with the output charge module to discharge the output filter module when the power source module is removed from the system cabinet. This invention allows for real-time monitoring of the power source module's status, enabling rapid activation of the output discharge module to lower the voltage across the output port below a safety threshold in a short period.
