Dual polarity 15V power supply

Dual polarity power supply

This simple split / dual polarity unregulated power supply circuit provides a +15 Volt and -15 Volt supply from a single transformer winding and one full-wave bridge.

A couple of zener diodes in series give you the voltage division and their centerpoint is grounded. (The filter capacitor should not be seated through its case). Since this power supply is unregulated type, so it will not recommended for high quality audio system.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
