There are also simple capacitive voltage doubler and Dickson multiplier circuits using diodes and capacitors to multiply a DC voltage by an integer value, typically delivering only a small current.
12.
The circuit works by alternately switching the output of each stage between a voltage doubler driven by \ phi _ 1 \ and one driven by \ phi _ 2 \.
13.
Many, but not all, voltage doubler circuits can be viewed as a single stage of a higher order multiplier : cascading identical stages together achieves a greater voltage multiplication.
14.
My position, in summary, is that the term " voltage doubler " is a stock phrase in the industry and refers to a specific class of circuits.
15.
For simple higher-frequency filter circuits, or in voltage regulator or voltage doubler circuits, low-cost metallized polyester film capacitors provide long-term stability, and can replace more-expensive tantalum capacitors.
16.
The diodes in this type of power supply will handle the DC current just fine because they are rated to handle double the nominal input current when operated in the mode, due to the operation of the voltage doubler.
17.
Interestingly, Greinacher also had to invent the practical voltage doubler circuit in order to provide the 200-300 V he needed for the ionometer as the 110 V AC supplied by the Zurich power stations of the time were insufficient.
18.
As " V " in becomes positive, the capacitor serves as a voltage doubler; since it has stored the equivalent of " V " in during the negative cycle, it provides nearly that voltage during the positive cycle.
19.
AC loads can occur in AC motor run capacitors, for voltage doubling, in snubbers, lighting ballast and for power factor correction PFC for phase shifting to improve transmission network stability and efficiency, which is one of the most important applications for large power capacitors.
20.
In areas using 110 120 volt AC, a simple half-wave rectifier limited the maximum plate voltage that could be developed; this was adequate for relatively low-power audio equipment, but television receivers or higher-powered amplifiers required either a more complex voltage doubler rectifier or warranted the use of a power transformer with a conveniently high secondary voltage.
