audio output transformer wiring color code

Two positive terminals of diodes make negative output pin and two negative terminals make positive output pin. In the bridge Rectifier, 4 diodes are used and connect each other in this way two terminals of negative and two terminals of positive of diodes meet each. Here This connected capacitor is known as a Filter capacitor but actually this is an Electrolyte capacitor. So use at least a 1000uF capacitor with the output for reducing the Noise. Without using capacitor Output has mush noise because not pure DC without a filter and a lot of Ripple noise not suitable for use. This connection is used for a full-wave rectifier circuit. Here DC will be Positive Output from diodes, and middle terminal of transformer directly connected for negative DC supply. Both wires connected with Positive Pin of Diode means AC 12v comes through the Positive terminals of diodes and output will from the negative terminal of diodes. In the 12-0-12 transformer connection, we use the input 220/230v on the primary side and if we use 2 diode for full-wave rectifier then both side wires of the secondary side connect with the diode and the middle (0v) wire direct connect with the load ground or negative supply. A 0-12 transformer only can be used for 12v supply whereas a 12-0-12 transformer can be used for a 24v supply. 0-12 transformer is also a 12v step-down transformer but it has only 2 wires or terminal from the secondary coil. 12-0-12 transformer is a center-tapped transformer. It has 3 output wires and this transformer also can be used for 24v supply. Difference between 12-0-12 and 0-12 transformerġ2-0-12 transformer is 12v step-down transformer that provides two wires with 12v each and one is 0v. The middle wire terminal is considered as 0v and Each side terminal from 0v is 12v. Input is 220 to 230v and output is 12v-0-12v. This type of transformer is also called a center tap transformer.

How we find which are primary (input) and which are secondary (output) wires/terminals of transformer–Ī 12-0-12 transformer is a 12v step-down transformer that has 3 terminals from secondary.

Why do we use capacitor as filter in rectification.
