As we know that that one limitation when we build a voltage doubler circuit is essentially reduces the output current capacity and makes for poor regulation because high output impedance. However, this may be turned into an advantage in that the output is inherently current limited. Note that in the case of current limiting, the current rating of the capacitors may need to be evaluated as they do have a finite AC component voltage rating and cannot tolerate excessive voltage without overheating.

In this article we will give you one electronic circuit of Voltage Doubler Power Supply Circuit using Classic Full-Wave Bridge Rectifier like in Figure 1 below. The main circuit in this article is how to modify bridge rectifier to other full-wave rectifier for voltage doubler.

Description

Circuit like in Figure 1 above show you about the Voltage Doubler Power Supply Circuit using Classic Full-Wave Bridge Rectifier that give you one reference circuit to build by yourself of voltage doubler using classic full-wave bridge rectifier now.

From Electroschematics site that the the classic voltage doubler (or cascade doubler as it is sometimes called) is limited in that it has line frequency AC ripple. Note that typical full-wave rectifiers have a twice line frequency ripple frequency on the filter capacitor. However, capacitors are inexpensive and can generally be doubled in size to reduce ripple voltage.
