Introduction

Jeong Ho Seo is a notable inventor based in Gwangju, South Korea, recognized for his contributions to the field of motor technology. With a total of two patents under his name, Seo has developed innovative solutions that enhance the efficiency and operation of appliances like refrigerators.

Latest Patents

Seo's most recent patents encompass a revolutionary BLDC (Brushless Direct Current) motor driving apparatus and a refrigerator utilizing this advanced technology. The patented motor driving apparatus optimizes compressor operation by incorporating temperature sensors that dynamically adjust the driving mode based on detected temperatures. This intelligent system allows for a general operation mode, where the motor is driven in a 120-degree conduction method, and a power-saving mode that employs a 90-degree conduction method. The latter effectively increases pulse width driving current, enabling low-speed operation during the refrigerator's power-saving mode.

Additionally, Seo introduces a phase commutation method for BLDC motors, which ensures precise detection of commutation timing and position. This advancement stabilizes the rotation and RPM of the compressor while minimizing noise and vibration. In this innovative method, the motor operates based on a scheme that replicates controls from previous phases, facilitating smooth transitions and efficient operation.
