Voltage Doublers
To obtain more d-c output voltage from a rectifier tube, the circuit of Fig. 53 is often used.
With proper values of circuit elements the output is nearly double the a-c peak voltage. Tube inverse peak voltage is little more than the d-c output voltage, and no d-c unbalance exists in the anode transformer. Current output available from this circuit is less than from the single-phase full-wave circuit for a given rectifier tube. Current relations are given in Fig. 52. Voltage tripling and quadrupling circuits also are used, either to increase the d-c voltage or to avoid the use of a transformer.(1)
