In addition, the
full-wave circuit provides better voltage regulation than the
half-wave circuit, since the latter relies upon one capacitor
(C1 in figure 1A.) to provide the charging energy to a single
DC load capacitor (C2 in figure 1A.). The full-wave circuit,
however, requires that the secondary side of the transformer
be capable of withstanding high voltages (approximately
1/2 of the output voltage). For this reason, the half-wave
multiplier is usually the preferred circuit when high voltage
outputs (V0 = kV) are required
