Hybrid Cockcroft-Walton Voltage Multiplier with Multiple Intermediate Single-Ended Output Nodes

This letter proposes a hybrid Cockcroft-Walton voltage multiplier featuring multiple intermediate single-ended output nodes, enabling the simultaneous generation of several DC voltage levels from a single converter. A closed-form steady-state formulation is derived to characterize the average output voltage at each node, explicitly accounting for the diode forward voltage drop while preserving analytical tractability suitable for system-level design. The resulting expressions admit a Thévenin-equivalent interpretation at each output node, providing direct insight into load regulation and design trade-offs. Such multi-output configurations are particularly attractive for reducing system complexity and component count in applications requiring distributed voltage levels. Experimental validation under different operating conditions demonstrates a reduction of more than 30% in the mean relative error compared to previous analytical formulations, confirming the effectiveness of the proposed approach for practical multi-output voltage multipliers.
