The primary disadvantage of this circuit is that stray capacitances are much more significant than with the Dickson multiplier and account for the larger part of the losses in this circuit
The transformer should provide 144-0-144 v to have a no-load voltage of 500 v dc in a voltage-doubler using two diodes.
a transformer
It's double the frequency of the power source.
With voltage control there is so much voltage drop due to resistor, that's the disadvantage
It has poor regulation and wastes energy.
What is the math in a voltage doubler without a transformer? how doesa voltage doubler without a transformer?

The voltage doubler works by charging alternate capacitors on alternate half-cycles. Since the capacitors are in series, the voltage doubles.

Do a web search for "voltage doubler" or "voltage multiplier" and you will find many solutions. For AC, using appropriate diodes and resistors in the proper configuration with a transformer will do the trick. There are "step up" transformers, which have a different number of windings on the primary and secondary coils. For DC circuits, you can obtain low-cost integrated circuits to effectively increase the input voltage. Look up "dc voltage doubler".
A: The purpose it to block the capacitor from discharging to the source
It's double the frequency of the power source.
full wave doubler works like a doubler but difference is in doubler you will get only double of your input. in full wave doubler you will get a doubler of your doubler...

The capacitor in a microwave oven, along with its associated high voltage diode, form what is called a voltage doubler to drive the magnetron.
This concept is too difficult (for me) to describe in words alone. There is a good article in wikipedia.org see 'voltage doubler'. There are several circuits.
Either electronically through a DC Bus similar to what is used in a Variable Frequency Drive, or through a Voltage doubler where resistors in parallel with a series r off of the p resistor acts as a voltage multiplier. Search for Voltage divider, or DC amplifier.
