Why don't the C1 and C2 capacitors discharge? [closed]
In the circuit, we know that when D1 is connected then the C1 capacitor is also in the circuit until it's fully charged. Why when D1 is disconnected and D2 and C2 are in the circuit, C1 can't ...

Voltage Doubler capacitance calculation
I have an astable multivibrator that produces 5 V square wave input to the push pull and the voltage doubler part of the circuit. Now somehow the simulation works at 0.1 uF capacitors for the voltage ...

How to select caps for voltage doubler at RF frequency for DC current output?
High-frequency AC transformer output hooked to half-wave DC voltage doubler. Current through is 6 A to LOW frequency switching load.
I assumed there was enough 20 kHz time to keep the second cap ...

Why does the voltage double in a doubler-circuit?
I’m having a hard time understanding how the final voltage is achieved.
I understand that in the first half of the sine wave the first capacitor gets charged to 1V.
In the 2nd half the first one is ...
