Title: Je Hyung Cho: Innovator in Power Systems and Motor Driving Technologies
Introduction
Je Hyung Cho is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of power systems and motor driving technologies. With a total of 6 patents to his name, Cho's work has had a considerable impact on the industry.
Latest Patents
Cho's latest patents include a power system and a motor driving apparatus. The power system is designed to include a first motor and a second motor connected in parallel. It features a driver that supplies a driving current to both motors and a controller that regulates the driver based on the driving current and the rotating speed of the first motor. Notably, if the rotating speeds of the two motors differ, the controller adjusts the driver to synchronize their speeds. This innovative design allows for the simultaneous operation of multiple motors at the same speed using a single driving apparatus.
The motor driving apparatus consists of an AC-DC conversion unit that rectifies AC power from an external source, a DC link unit that stabilizes the rectified voltage, and a DC-AC conversion unit that supplies AC power to a motor using the stabilized DC voltage. The DC link unit incorporates film capacitors to eliminate voltage ripple, while the DC-AC conversion unit utilizes a 3-level inverter to deliver AC power to the motor.
