Title: Innovations of Dingkun Du in Power Conversion Technology
Introduction
Dingkun Du is a prominent inventor based in Santa Clara, CA, known for his significant contributions to power conversion technology. With a total of six patents to his name, Du has made remarkable advancements in the field, particularly in the design and functionality of power converters.
Latest Patents
One of Du's latest patents is titled "Adaptive on-time generation for three-level power converters." This invention involves a power converter circuit that includes multiple devices and a switch node connected to a regulated power supply node via an inductor. During the first time period, the power converter charges a capacitor and then couples the capacitor to the switch node during a second time period. In the third time period, the power converter connects the switch node to an input power supply node. To ensure a constant charge is delivered to the load, the duration of the third time period is adjusted based on various voltage levels and the inductor's value.
Another notable patent is "Cycle transitions for buck converter circuits." This voltage regulator circuit also includes multiple devices and a switch node linked to a regulated power supply node through an inductor. The circuit charges a capacitor using an input power supply signal and couples the capacitor to the switch node using selected devices based on control signals. A control circuit generates these signals based on a specific switching sequence, which is determined by the voltage levels of the regulated power supply node and the input power supply signal.
