AC power sources provide output often with adjustable ranges of current, voltage and frequency. They are used in testing motors and many other kinds of electrical equipment for which input values may ...

Next, an inverter circuit converts this DC back to AC, allowing engineers to make any phase on the motor positive or negative and generate any desirable frequency. The current source inverter type ...

A great example is this simple wireless AC current detector from [NEW PEW]. The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 ...
