The number of turns of the secondary winding of the transformer will increase when the conventional high-voltage output power supply is boosted by a transformer

resulting in the charging and discharging current and noise during working hours

and the energy loss of the primary side and secondary side of the transformer as well. In order to solve this problem

the power electronics technology and voltagedoubling rectification method were used to analysis two common voltage-doubling rectification circuits

the half-wave voltage-doubling rectification and the Schenkel voltage-doubling rectification. The characteristics of the two voltage-doubling rectification circuits were compared by the simulation and analysis. Compared with the half-wave voltage-doubling rectification circuit

the Schenkel voltage-doubling rectification circuit had a much smaller output ripple voltage

a shorter output voltage setup time and a higher output voltage.
