Adaptive On-Time Generation for Three-Level Power Converters - A simplified explanation of the abstract
This abstract first appeared for US patent application 17482287 titled 'Adaptive On-Time Generation for Three-Level Power Converters
Simplified Explanation
The abstract describes a power converter circuit in a computer system that includes multiple devices and a switch node connected to a regulated power supply node through an inductor. The power converter charges a capacitor during a specific time period and then connects the capacitor to the switch node during another time period. In a third time period, the power converter connects the switch node to an input power supply node. To ensure a constant charge delivery to the load, the duration of the third time period is adjusted based on various factors such as the voltage levels of the input power supply node and the regulated power supply node, the value of the inductor, and the durations of the first and second time periods.

Original Abstract Submitted
A power converter circuit included in a computer system may include multiple devices and a switch node coupled to a regulated power supply node via an inductor. During a first time period, the power converter charges a capacitor, and the couples the capacitor to the switch node during a second time period. During a third time period the power converter couples the switch node to an input power supply node. To maintain constant charge delivered to the load during each time the switch node is coupled to the input power supply node, the duration of the third time period is adjusted based on a voltage level of the input power supply node, a voltage level of the regulated power supply node, a value of the inductor, and the durations of first and second time periods.
