With a total of four patents to his name, he has developed innovative solutions that enhance the functionality and efficiency of various electrical systems.

Latest Patents

One of Young-Kee Min's latest patents is an LED driver that serves as a power supply for LED light sources. This power supply is designed to accommodate a variable number of LEDs wired in series and/or in parallel. It utilizes current and voltage feedback to adjust the power supplied to the LEDs while providing essential protection to the light source. The feedback controller compares sensed current and voltage to a reference signal, generating a feedback signal that is processed by a power factor corrector to regulate the current flow through the transformer supplying power to the LEDs. Additionally, a LED control switch clamps the peak current to the LEDs, offering further protection. A short/open detection circuit is also included to indicate any 'LED outage' in the light source.

Another significant patent involves a load and speed sensitive motor starting circuit and method. This invention measures the main motor winding voltage and detects points in the electromagnetic wave cycle where this voltage crosses zero. It also measures auxiliary motor winding voltage, comparing phase shifts in the auxiliary winding to facilitate starting and restarting. The invention ensures that the auxiliary winding is disconnected when the zero current crossing points fall outside a specified window pulse, and it reconnects when the zero voltage crossing points align with another window pulse.
