Circuit Simulator - Voltage Doubler
Voltage Doubler
Circuit Description:
This circuit uses some diodes and capacitors to generate 28 V from an 15 V input signal. The current from the input flows through the upper diode in one direction, charging the upper capacitor; the diode prevents the capacitor from being discharged when the input signal goes negative. The bottom diode/capacitor pair works the same way for the negative portion of the input cycle.

This circuit only works for higher voltages.. that is for greater than 10v.. if u check it for 1v.. it wont give higher voltage..

Does input frequency have any effect on the voltage?

For any given cap size, input freq will alter current that can be taken out. Remember this is a charge pump, which can only dump one capacitor full of charge per cycle.

Does load resistance do have any effect on output voltage?

Any type of diodes will work in this circuit but it depends on switching speed., 1n4148 diode will work better.

@Mubarak: Silicon diodes "open" at voltages between 0.6 and 0.8V. So both diodes will "eat" about 1.6V. If the input is below that threshold there will be nothing left to amplify.
