I have an AC to DC voltage doubler circuit. I am using a full wave bridge rectifier that uses two diodes and two capacitors that are 470uFarad each. My supply is a 50 watt transformer that outputs 13.9 volts and 3.790 amps. The supply frequency is 60 hz. The output frequency is 120 hz from the rectifier. The voltage output is 3.72 volts DC at 1.650 amps DC. I already know that the power supply is too low for the load I have which has a resistance of 2.3 ohms. My question is how do I calculate the power required to be able to allow the doubling effect to happen?
