A voltage doubler is an electronic circuit that produces twice the input voltage by charging a capacitor from the input voltage. Figure 3256 shows one of the simplest circuits, composed of a transformer, a capacitor, and a diode. We assume that with AC input the capacitor is always charged at +10 V due to the diode. When A (green) is at +10 V, then B (red) is at +20 V because the transformer and capacitor are in series, while B is at 0 V when A is at -10 V. Therefore, the output voltage at B is twice the voltage at A. Note that the voltage at B is still an AC voltage.
