TOP 3 How to make a high efficiency voltage doubling circuit without coils

In this presentation I explain, in my own way and without pretension, what you need to know to transform a sinusoidal voltage into a direct voltage. This is the first part. I start by exploring the essential bases to know without going into the major theories and different approaches to the “recovery” part. Good viewing !

How to EASILY make a voltage doubler, with 2 diodes and 2 capacitors.

The two capacitors charged to the peak voltage, i.e. the effective voltage x 1.41, behave like two DC voltage generators in series.

Obviously, the value of the output voltage in the presence of a load depends on the capacitive value of the capacitors and the exact value is linked to the frequency and the time constant of the circuit of use.

The output current must not exceed the maximum current supported by a rectifier, and as said above, the voltage supported by each of the capacitors is equal to the effective voltage x 1.414, or half the output voltage. Note that each rectifier is subjected to a peak reverse voltage equal to the rms voltage x 2.82. Christian.D
