Abstract :
The 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 given in the Z-transform. The main characteristics and general formulae of the multiplier with an arbitrary number of cells are derived. The expressions of cut-off frequency, gain and output impedance are given, and module and phase frequency responses are plotted
