ABSTRACT:
A power converter, for accepting power from a source and delivering power to a load, comprises conversion circuitry including a first side coupled to the source and a second side isolated from the first side and coupled to the load, energy storage circuitry, connected to the first side of the conversion circuitry, for storing energy at a voltage higher than the voltage of the source, and a switch arranged with respect to the conversion circuitry and energy storage circuitry to allow energy to be delivered from the source to the energy storage circuitry and a quantum of energy to be delivered to the second side of the conversion circuitry during a time that the switch is closed. Energy can be delivered to the energy storage circuitry and the quantum of energy delivered to the second side of the conversion circuitry during less than the entire time that the switch is closed. A method for use in converting power from a source to a load comprises closing a switch, receiving energy from the source during at least a portion of the time that the switch is closed for storage in a first circuit at a voltage higher than the voltage of the source, and transferring, during at least a portion of the time that the switch is closed, a quantum of energy stored in the first circuit to a second circuit that is coupled to the load and is isolated from the first circuit.
