Introduction

Sung-Yun Park is a notable inventor based in Bucheon, South Korea. He has made significant contributions to the field of semiconductor technology, particularly in the development of control devices for power switches. With a total of 5 patents to his name, Park continues to push the boundaries of innovation in his industry.

Latest Patents

One of his latest inventions is a switch control device that manages the switching operation of a power switch. This device includes an auxiliary power device that features a parasitic capacitor. The auxiliary power device charges the parasitic capacitor by receiving a power voltage, which generates an auxiliary power voltage. The switch control device also incorporates a control pulse generator that is driven by the auxiliary power voltage. This generator produces a set pulse and a reset pulse based on an input signal, which is crucial for controlling the switching operation of the power switch. Additionally, the device generates a gate signal that activates the power switch in synchronization with the set pulse and another gate signal that deactivates the power switch in synchronization with the reset pulse.

Another significant patent involves a control device for an LED light-emitting device. This invention relates to the switching operation control of a power switch, the LED light-emitting device that includes the control device, and the associated control method. The control device detects the zero crossing time when the voltage at the input end of the power switch reaches zero. It generates a reference signal synchronized with the input voltage and compensates this signal with a first voltage that exceeds zero during the blocking period corresponding to the zero crossing time.
