An autotransformer has a single winding with two end terminals and one or more terminals at intermediate tap points. It is a transformer in which the primary and secondary coils have part of their turns in common. The portion of the winding shared by both the primary and secondary is the common section.
The output (secondary) winding has a center tap connected to a grounded neutral. As shown in Fig. 1, either end to center has half the voltage of end-to-end. Fig. 2 illustrates the phasor diagram of the output voltages for a split-phase transformer. Since the two phasors do not define a unique direction of rotation for a revolving magnetic ...
Valve circuits for quality reproduction have long been produced with no other (inter-stage) audio transformers, but an output transformer is needed to couple the relatively high impedance (up to a few hundred ohms depending upon configuration) of the output valve(s) to the low impedance of a loudspeaker. (The valves can deliver a low current at ...
For example, a 24 VCT transformer will measure 24 VAC across the outer two taps (winding as a whole), and 12 VAC from each outer tap to the center-tap (half winding). These two 12 VAC supplies are 180 degrees out of phase with each other, measured with respect to the tap, thus making it easy to derive positive and negative 12 volt DC power ...
At the same time, the other transistor is OFF, its current is zero while its voltage is a half-sine (peak = Vin * PI). The transistors direct the input current into each of the primary windings of the transformer alternately in turn. The opposing currents in the primary windings always balance but the whole primary "sees" the complete sinewave.
One can observe that the output stage of the successful McIntosh amplifier is a circlotron too because the special winding of the output transformer eliminates one of the two floating power supplies. The concept was resurrected in its transformerless form in early 1980s by Ralph Karsten , founder of Atma-Sphere , which remains the principal ...
The phase coils are traditional wound in a single coil assembly with the 0 to 50% winding section buried below the 50% to 100% windings in a single thermal mass as shown in figures 2 and 3 Figure 4. 3 Coil Assembly. Figure 4 shows an improved 1000 kW 11,000 Volt motor starter autotransformer with Axial cooling fans, Cast resin encapsulated coils,
Switchmode PSU for car audio 12V to symmetric output push–pull converter used for powering car audio amplifiers. This is a true push–pull topology with two switches and a center-tapped transformer.
