This paper includes a Cockcroft-Walton (CW) high phase dc-dc voltage transition based on multiplier, with no step-up transformer. The suggested conversion approach is very appropriate for low-input dc generating systems with continuous input current on a switch, diode or condenser with a low rib, high voltage and low voltage. In this article two frequencies in the suggested control techniques are used, one works with high frequencies in order to reduce the inductor size, the other works with a comparatively low frequency based on the rip of the target voltage.
