Abstract: A level shifter causes a switch to open or close by selecting one of two stored logical values to generate a gate-drive voltage to cause a transition in the switch.
Abstract: An apparatus for power conversion comprises a voltage transformation element, a regulating element, and a controller; wherein, a period of the voltage transformation element is equal to a product of a coefficient and a period of the regulating circuit, and wherein the coefficient is selected from a group consisting of a positive integer and a reciprocal of said integer.
