A modulation transformer is an audio-frequency transformer that forms a major part of most AM transmitters. The primary winding of a modulation transformer is fed by an audio amplifier that has about 1/2 of the rated input power of the transmitter's final amplifier stage.
Transformers [ edit ] In transformers magnetic noise and vibrations are generated by several phenomena depending on the load case which include Lorentz force on the windings, [ 12 ] Maxwell forces in the joints of the laminations, and magnetostriction inside the laminated core.
Typical push–pull audio tube power amplifier, matched to loudspeaker with an impedance-matching transformer. Audio amplifiers typically do not match impedances, but provide an output impedance that is lower than the load impedance (such as < 0.1 ohm in typical semiconductor amplifiers), for improved speaker damping.
Output transformerless (OTL) is a type of vacuum tube audio power amplifier, which omits an output transformer for the purpose of greater linearity and fidelity. Conventional vacuum tube amplifier designs rely upon an output transformer to couple the amplifier's output stage to the loudspeaker.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
What is a transformer? A transformer converts electricity from one voltage to another. Transformers can be found at various points in the electric grid. In some spots, they step up voltage for ...
