The dynamics of the Cockcroft-Walton voltage multiplier

A description of the small-signal dynamics of the Cockcroft-Walton voltage multiplier is obtained through state-space modeling in discrete time. Its small-signal equivalent circuit is a two-port linear network whose four transfer functions are expressed in the z-transform domain. General formulae for the multiplier with an arbitrary number of cells are derived; expressions for prime parameters such as the cut-off frequency, gain, and output resistance are given, and frequency dependences of module and phases are plotted.<
