Title:
HIGH-EFFICIENCY HYBRID REGULATOR
Document Type and Number:
WIPO Patent Application WO/2023/161709
Kind Code:
A1
Abstract:
An embodiment provides a regulator comprising: a switch network which includes a first switch block, a second switch block, a third switch block, and a fourth switch block, which are connected to each other in series, wherein a flying capacitor is connected to a node at which the first switch block and the second switch block are connected and to a node at which the third switch block and the fourth switch block are connected, and an inductor is connected to a node at which the second switch block and the third switch block are connected; and a control circuit which can control the switch network to a first state in which the first switch block and the second switch block are turned on, a second state in which the third switch block and the fourth switch block are turned on, a third state in which the first switch block and the third switch block are turned on, and a fourth state in which the second switch block and the fourth switch block are turned on, and which controls the switch network such that the third state and the fourth state, in which inductor current forms a resonant waveform, alternate, and controls, when the magnitude of the inductor current is out of a required range, the switch network such that the first state or the second state is between the third state and the fourth state.
