Title: Kwang Woon Lee: Innovator in Linear Compressor Technology
Introduction
Kwang Woon Lee is a notable inventor based in Suwon, South Korea. He has made significant contributions to the field of compressor technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is for a linear compressor and apparatus to control the same. This invention allows the frequency of a drive current supplied to a drive motor to synchronize with a resonance frequency that varies according to load fluctuations in real time. This synchronization achieves maximum efficiency for the linear compressor. The design includes a drive motor, a piston that reciprocates due to the motor, and a control unit that generates a reference current with a 90° phase difference relative to the piston’s displacement waveform. This innovative control mechanism ensures that the drive current aligns with the resonance frequency of the piston.
Another significant patent by Kwang Woon Lee is a startup control method for brushless DC motors (BLDC). This method effectively prevents the generation of transient currents, thereby reducing vibrations during the startup phase. The approach allows for a stable transition into a sensorless operation mode, minimizing the startup failure rate of the BLDC motor. The method involves commutating the current applied to the stator windings based on the rotor position, ensuring efficient operation.
