A performance study of a 3-phase symmetric Cockcroft-Walton (CW)-multistage voltage multiplier (VM) is proposed. It consists of 1 smoothing column and 6 oscillating columns. The oscillating columns are connected to a 3-phase power through center-tap transformers. The capacitors of the smoothing column are charged 6 times per cycle by 6 oscillating columns and are discharged 6 times through the load, unlike the conventional symmetric VM in which they are charged and discharged twice per cycle. The 3-phase symmetric structure completely eliminates the first 5 harmonic components of load-generated voltage ripple. Theoretic analysis indicates that the proposed 3-phase symmetric CW-VM has one-third the voltage ripple and voltage drop of the conventional single-phase symmetric CW-VM. Simulation results of the proposed 3-phase symmetric CW-VM as well as those of the conventional single-phase symmetric CW-VM are presented. A comparison shows that the 3-phase symmetric CW-VM has significantly less voltage ripple, half the voltage drop, and a 4-fold increase in the output power over the conventional single-phase symmetric CW-VM.
