Patent ID: 10075067

Abstract:
Various examples are provided for two-switch switched-capacitor (SC) converters. In one example, a SC converter includes first and second switches connected in series, a first gain-extension network coupled to the first switch and a second gain-extension network coupled to the second switch, which can be operated to boost a voltage applied across the first and second switches. The gain-extension networks can include a diode and a capacitor. In another example, the gain-extension networks can include a switch and a capacitor, which can be operated to buck a voltage applied across the gain-extension networks. In another example, a SC converter includes first and second diodes connected in series, a first gain-extension network coupled to the first diode and a second gain-extension network coupled to the second diode. The gain-extension networks can include a switch and a capacitor, which can be operated to buck a voltage applied across the gain-extension networks.
