# Center tap transformer for transistor amplifier.

## Center tap transformer for transistor amplifier.

What is the transformer?  transforms is a electrical energy from one circuit to another without any direct electrical connection. We had to use the transformer to everywhere. but nowadays we can use SMPS circuit also. in SMPS also have the center tap. Normally we use Positive and Negative voltage transformer. but center tap has 3 output. Positive, Negative and Ground Voltage. we need this transformer for making the amplifier. normally in a transformer has primary and the secondary wire. for primary we use AC 110v/220 voltage. and we can get output from secondary what’s we need. here secondary has 2 wire output. But in a center tap transformer has 3 wire for the output voltage.

## Toroidal transformer

What is center tap transformer? we can see in this photo there has 3 output wire for secondary. and also we can see the use of this transformer to making AC to DC Voltage. here used a Diode for convert the voltage AC to DC. and also we can see how to use 6 capacitors for the voltage.

The center tap transformer has 3 secondary output. 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.

## Let’s Watch the Video to making the voltage.

Here in this video, we can learn how to make center tap voltage.

When we calculate the wattage of the amplifier, is this base on psu dc volt or ac volt multiply ampere of course number of the power transistor in a circuit. Respectfully yours, Rick
