Center tap transformer

Hey folks Here's a way to create a center tapped transformer fullwave power supply without having to ground the AC source to the same ground as the DC secondary ground ckt. The ckt often does not work. Just ground the AC source to ground thru a small capacitor. I often use a 10nf capacitor. This will satisfy EveryCircuit's requirement to ground the AC source to function properly.

Any size cap will do. Its just to fool the simulation to bypass the initial dc calculation.

You must be careful....I chose a small value because the reactance(ac resistance) is so high that it has virtually no affect on the ckt. A large cap, in microfarads, will conduct some 60Hz energy
