In order to obtain still higher voltages with rectier-condenser
circuits, several full wave doublers have been stacked on top of —
‘
each other.
Machines have also been built using a multiplicity
of Villard circuits (B in gure 13—4). However, the problem of
insulation between the primary and secondary of those transformers in the higher voltage parts of the circuit limits the application of these ideas. In H of gure 13—4, the condensers are so
