Center tap transformer for the amplifier.
What is the transformer? transforms electrical energy from one circuit to another without any direct electrical connection. We had to use the transformer everywhere. but nowadays we can use SMPS circuits also. in SMPS also have the center tap. Normally we use Positive and Negative voltage transformers. but the center tap has 3 outputs. Positive, Negative, and Ground Voltage. we need this transformer for making the amplifier. normally a transformer has a primary and secondary wire. for primary we use AC 110v/220 voltage. and we can get output from secondary what we need. here secondary has 2 wire outputs. But a center tap transformer has 3 wires for the output voltage.
What is a center tap transformer? we can see in this photo there have 3 output wires for the secondary. and also we can see the use of this transformer to make AC to DC Voltage. here used a Diode to convert the voltage from AC to DC. also we can see how to use 6 capacitors for the voltage.
The center tap transformer has 3 secondary outputs. the middle one is for ground voltage. another two for making the positive and negative voltage using the diode.
For transistor amplifier need center tap voltage. Positive, Negative, and the ground Voltage.
