In the figure we have the configuration of a voltage regulator with 3 transistors. The components depend on the desired voltage and current as well as on the characteristics of the transistors.
We found this circuit in a 1977 radio documentation. The circuit uses TTL frequency dividers from...
In figure we have a three-phase AC motor control for voltages up to 600 V or 1200 V depending on...
The oscillator shown in the figure can generate signals up to 500 kHz and has good stability. Coil...
