We’ve now spent several months in this series journeying through the world of audio, and along the way we’ve looked at the various parts of a Hi-Fi system from the speaker backwards to the source.

While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT).

Constant voltage transformers (CVTs), or ferroresonant transformers, produce a constant secondary (output) voltage for varying primary (input) voltages within a certain range. With CVTs, the ...

The type of driver has a large influence on the stepper motor system's overall performance, specifically its torque ... Stepper motor performance is also very dependent on the drive circuitry, which ...

Its menu system is easy to navigate ... Disposable batteries maintain a more constant voltage before dying (usually 1.5 volts), while rechargeables keep running at a lower voltage (dipping ...

A direct current flows in only one direction. On a voltage-time graph this would appear as a straight horizontal line at a constant voltage. Car batteries, dry cells and solar cells all provide a ...
