Two Different Full-wave Rectified Voltages From Center-tapped Transformer and Bridge Rectifier 2016-08-01

Below is a simple way to get two full-wave rectified voltages from one center-tapped transformer and one bridge rectifier.
Adding a capacitor filter at the center-tap gives roughly half the DC voltage available from the center-tap output to ground as compared to the bridge output.

This can be handy for example, if you want to build a power supply with two different output voltages, such as 5v, along with a higher voltage, such as 10-12V. This minimizes dissipation in the 5V and 10-12V...
