Latest Patents
One of Han-Suk Seo's latest patents is an over-voltage protected battery charger with bypass. This innovative battery charger includes charging circuitry that provides a battery charging voltage responsive to an input voltage. The first circuitry offers both over-voltage protection and an input voltage bypass signal. It features a low impedance switch with a resistance of at least 500 mΩ for connecting the input voltage to an output voltage node. Additionally, it includes a higher impedance switch with a resistance of at least 1000 mΩ for providing the input voltage as a voltage bypass signal.
Another significant patent is the half-bridge power converter system and method of operation. In this embodiment, the power converter generates an output voltage by modulating an input voltage through the operations of a first switch and a second switch arranged in a half-bridge configuration. The power converter is equipped with a switch driver circuit that controls the turning on and off of the first and second switches. A PWM controller generates a switch driver control signal to manage the switch driver circuit based on the output voltage. The switch driver circuit also produces an on-time control signal to turn off the first switch after it has been activated for longer than a threshold period.
