  • Patent number: 11646657
    Abstract: In a power converter, a switching network having switches that operate at a common frequency and duty cycle interconnects circuit elements. These circuit elements include capacitors that are in a capacitor network and a magnetic filter. When connected to the capacitors by a switch from the switching network, the magnetic filter imposes a constraint upon inter-capacitor charge transfer between the capacitors to maintain the filter's second terminal at a voltage. The switching network transitions between states. These states include a first state, a second state, and a third state. In both the first state and the third state, the first magnetic-filter terminal couples to the capacitor network. In the second state, which occurs between the first and third state, the switches ground the first magnetic-filter terminal.

  • Patent number: 11552560
    Abstract: An apparatus includes first and second pluralities of switches, a controller for controlling these switches, gate-drivers for driving switches from the first plurality of switches, and first and second terminals configured for coupling to corresponding first and second external circuits at corresponding first and second voltages. During operation, the controller causes the first plurality of switches to transition between states. These transitions result in the second voltage being maintained at a value that is a multiple of the first voltage. The controller also causes the second plurality of switches to transition between states. These transitions resulting in capacitors being coupled or decoupled from the second voltage. The gate drivers derive, from the capacitors, charge for causing a voltage that enables switches from the first plurality of switches to be driven.

  • Patent number: 11496046
    Abstract: An apparatus for power conversion includes a switching network that controls interconnections between pump capacitors in a capacitor network that has a terminal coupled to a current source, and a charge-management subsystem. In operation, the switching network causes the capacitor network to execute charge-pump operating cycles during each of which the capacitor network adopts different configurations in response to different configurations of the switching network. At the start of a first charge-pump operating cycle, each pump capacitor assumes a corresponding initial state. The charge-management subsystem restores each pump capacitor to the initial state by the start of a second charge-pump operating cycle that follows the first charge-pump operating cycle.

  • Patent number: 11336175
    Abstract: Operating a charge pump in which switches from a first set of switches couple capacitor terminals to permit charge transfer between them and in which switches from a second set of switches couple capacitor terminals of capacitors to either a high-voltage or a low-voltage terminal includes cycling the switches through a sequence of states, each state defining a corresponding configuration of the switches. At least three of the states define different configurations of the switches. During each of the configurations, charge transfer is permitted between a pair of elements, one of which is a first capacitor and another of which is either a second capacitor or the first terminal.
