The addition of still another diode-capacitor section to a Voltage trippler, as shown in Below Figure, produces an output four times the peak secondary voltage. C4 charges to 2Vp through D4 on a negative half-cycle. The 4Vp output is taken across C2 and C4, as shown. In both the tripler and quadrupler circuits, the PIV of each diode is 2Vp.

Factors affect Voltage Level Selection in Service System
Some of the factors that effect the selection of nominal voltage levels for the service systems are: Type and size of the load to be ...
