Latest Patents

Heon-Kyu Kim holds a patent for a groundbreaking invention titled "Fixed off time and zero voltage switching dual mode power factor correcting converter." This innovative dual mode converter operates in two modes: a variable-frequency naturally-commutated controller in Zero-Voltage-Switching mode and a fixed-off-time controller in Fixed-Off-Time mode. The design features four essential functional elements. A reference and biases element generates necessary voltage references and biases to determine various signal states. The Timing element produces a fixed off time signal and a voltage ramp signal that facilitate the operation in dual modes. Furthermore, a Catastrophic-Event element is incorporated to detect events that inhibit the converter output, thereby enabling the controller to be restarted. Lastly, the Mode Detection and Pulse Width Modulation element ascertains the operational mode based on signal inputs from the other components while modulating the output accordingly. In its primary mode, the controller leverages variable frequency operation for delivering main power, while in standby mode, it provides low power output, consuming less than 5W.
