摘要： This application relates to the field of circuit technologies, and provides a charge pump circuit, a power management circuit, and a terminal, to prevent a backflow current from being transmitted in the charge pump circuit. The charge pump circuit includes a first auxiliary circuit, a second auxiliary circuit, an input end, an output end, and a first boost circuit and a second boost circuit connected in parallel. The first boost circuit and the second boost circuit are electrically connected between the input end and the output end. When the charge pump circuit is in an operating state, the first boost circuit and the second boost circuit are separately configured to: receive a power supply voltage input by the input end, and boost the power supply voltage. Alternatively, when the charge pump circuit is in a non-operating state, the first boost circuit is further configured to be disconnected under control of a cut-off signal input by the first auxiliary circuit; and the second boost circuit is further configured to be disconnected under control of a cut-off signal input by the second auxiliary circuit.

摘要： An apparatus such as a power converter includes: a first capacitor; a second capacitor; a network of switches operative to control generation of an output voltage via: i) resonance of the first capacitor and a first transformer winding supplying first current to an output node of the power converter, and ii) resonance of the second capacitor and a second transformer winding supplying second current to an output node of the power converter. The first current may be substantially equal to the second current. The power converter may include additional windings in which other currents are substantially equal.

摘要： An apparatus for electric power conversion comprises an AC switching network connected to a regulating circuit comprising an inductor. The regulating circuit maintains an average DC current through the inductance. The AC switching network comprises switches that, when connected to charge-storage elements, define a switched-capacitor network, wherein the switches are controllable to switch between switching configurations such that, when the switching network is connected to charge-storage elements, each switching configuration defines a different arrangement of charge-storage elements in the switched-capacitor network. The switched-capacitor network transitions between first and second arrangements of the charge-storage elements so as to cause a transformation between an AC voltage on a first port of the switching network and a voltage with a non-zero average voltage on a second port of the switching network.
