Audio Transformer Symbol

Generally when we study about transformers we assume that the primary and secondary voltage and currents are in phase.

Audio transformer symbol. Get an idea about autotransformer its design types features applications auto transformer starter 3 phase auto transformer examples. This unique winding methodol ogy combined with top quality materials and exhaustive attention to detail add up to flat phase and frequency. This is the most common type of transformer widely used in electric power transmission and appliances to convert mains voltage to low voltage to power electronic devices. Af transformers are still produced however for a range of audio functions.

The winding polarity in a transformer is denoted by the dot convention. Metals normally used for conductors or for transformer cores possess one but not both of these properties therfore special metal alloys are used for screening cans that combine low resistivity and low reluctance. Constructing audio transformers that sets them apart from virtually all others. If the current enters the primary dotted terminal the voltage induced in the secondary dotted terminal will be positive.

Many are similar in construction to the power transformers described in module 11 3 but are often much smaller see fig 11 4 1.

Any electrostatic fields are then effectively conducted away from the transformer.

In audio applications tapped autotransformers are used to adapt speakers to constant voltage audio distribution systems and for impedance matching such as between a low impedance microphone and a high impedance amplifier input.
