Abstract

The present application relates to a resonant Dickson converter and its control method and driving integrated circuit. At least some of the exemplary embodiments are methods comprising: driving the voltage output of a Dickson converter by a resonant current through a first branch during a first on-time, the resonant current having a resonant half-period ; during the second on-time, the voltage output is driven by the resonant current through the third branch, the resonant current through the third branch has a resonant half period; and then the first branch and the third branch are electrically isolated; in the first dead zone detecting that the first on-time differs from the resonant half-cycle of the first branch during a period of time; and adjusting the first on-time used in subsequent cycles of driving the resonant current, the adjustment causing the first on-time to more closely match the first on-time Resonant half-period of a branch.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application 62 / 665,294, entitled "Predictive Resonance Control for a Dickson Converter," filed May 1, 2018. This provisional application is hereby incorporated by reference as if fully reproduced below. technical field [0003] The present application relates to the technical field of power converters, in particular resonant Dickson converters. Background technique [0004] Many applications use reduced voltage power converters. For example, in a server room with rack-mounted server blades, power may be distributed to each rack as a direct current (DC) voltage and then utilized by the server blades within each rack. However, as server capacity increases, power consumption also increases. To provide more power as server capacity increases, in some cases the industry has increased the DC distribution voltage used to distribute power to each rack (e.g., from 12 vo...
