Classification of the transformer? 2 type of voltage needs for making an amplifier. one is the half-wave transformer and another one is full wave transformer. here we use the step-down transformer. some amplifier need only positive and negative voltage. for this kind of amplifier, we use half wave transformer. it’s secondary has 2 wire for making voltage. we use one bridge diode or 4 pieces diode to making voltage. and we use one capacitor. another is full wave transformer. it has 3 secondary wire for the making voltage. high watts amplifier needs this full wave transformer. here we also use one bridge or 4 pieces diode for making voltage. and also we use 2 capacitors. because we need Positive voltage, Ground voltage, and Negative voltage.
here we are going to watch a video that how to make center tap voltage by using a half wave transformer?
