Multi-Level Power Converter with Hysteretic Control - A simplified explanation of the abstract
This abstract first appeared for US patent application 17485003 titled 'Multi-Level Power Converter with Hysteretic Control
Simplified Explanation
The patent application describes a multi-level power converter with hysteretic control. It includes a switching circuit and a control circuit. The switching circuit consists of switches, a capacitor, and a switch node connected to a regulated supply voltage node through an inductor. The control circuit activates specific switches based on the current switch state, compares the output current of the switching circuit to threshold values, and determines the next switch state using the comparison results and duty cycle information. It then transitions from the current switch state to the next switch state by activating a different set of switches.

Original Abstract Submitted
A multi-level power converter with hysteretic control is disclosed. In one embodiment, a power converter includes a switching circuit and a control circuit. The switching circuit includes a plurality of switches, a capacitor, and a switch node coupled to a regulated supply voltage node via an inductor. The switching circuit is configured to couple the switch node to different circuit nodes according to different switch states. The control circuit is configured to activate a particular set of switches according a current switch state, perform a comparison of an output current of the switching circuit to various threshold values, and determine a next switch state using results of the comparison and duty cycle information. Based on these results, the control circuit is configured to cause a transition from the current switch state to the next switch state by activating a different set of switches according to the next switch state.
