Latest Patents
One of his latest patents focuses on "Shoot-through prevention in switched-mode power supplies." This invention provides a system that operates a flyback converter. During the activation of a synchronous rectifier (SR) controller on the secondary side of the power converter, the system temporarily disables the driving of a gate of a metal-oxide-semiconductor field-effect transistor (MOSFET) by the SR controller. This allows for synchronization of the SR controller to a switching frequency on the primary side of the power converter. After a pre-specified period, the system re-enables the driving of the gate of the MOSFET by the SR controller.
Another notable patent is related to "Controlling a current drawn from an adapter by a computer system." This apparatus controls the current drawn from an adapter by a computer system. During operation, it senses the current using two current sensors, where the first sensor has a faster response time than the second. When the current sensed by the first sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, if the second sensor detects a current exceeding a predetermined thermal-limit current, the apparatus limits the current to this thermal-limit value.
