US 11,699,953 B2 · Zero voltage switching hybrid voltage divider

Abstract

Methods, systems, and apparatuses for efficient power supply and voltage division are described. Specifically, the described zero-voltage switching hybrid voltage divider (ZVS-HVD) may implement capacitor-inductor switching (e.g., a capacitor-inductor switching combination) to provide a zero-voltage switching bidirectional voltage divider converter. The ZVD-HVD may be implemented, in the example of a two-to-one ratio divider, via a configuration of three switches, three capacitors, and two small size inductors (e.g., to achieve zero voltage switching in any condition). In some examples, the ZVS-HVD may be realized via two of the switches sharing a same switching signal (e.g., the two-to-one ratio divider example of the described ZVS-HVD may be associated with two circuit states via the three switches). The described ZVS-HVD may support continuous input current, parallelizability, insensitivity to parasitic inductance, and high efficiency (e.g., reduced energy loss) at light load, among other features.
