Latest Patents
One of his latest patents focuses on high-side n-type power transistor gate driving techniques without a bootstrap capacitor. This innovation involves techniques and apparatus for effectively driving the gate of a high-side transistor in SMPS circuits, such as inverting buck-boost converters or buck converters. The technique employs a multi-step approach to pull down the gate voltage of the high-side transistor, initially discharging it to a lower voltage level. Once the gate voltage falls below a certain threshold, an auxiliary switch can take over to completely turn off the high-side transistor.
Another notable patent by Kwak addresses gate driving techniques to lower switch on-resistance in switching converter applications. This patent outlines methods and apparatus for driving transistor gates in SMPS circuits. The power supply circuit includes a switching converter with a switching transistor and a gate driver, which features multiple switching devices and a voltage clamp to optimize performance.
