This letter shows that a coupled-inductor suppresses the output voltage ripple in the Cockcroft-Walton (CW) circuit. The coupled-inductor plays two roles: boost of the output voltage by resonance with the parasitic capacitance in the CW circuit and suppression of the output voltage ripple. First, the amplitude and phase of the output voltage ripple in the CW circuit are theoretically derived. Then, a design procedure for the coupled-inductor is shown. The experimental results demonstrate the effectiveness of the proposed method.
