This circuit from an old documentation includes the power supply for the 117 V power grid. It can be adapted to other networks by changing the 10k resistors.
In this circuit we show how it is possible to control a high power load (which depends on the...
The transistors T1 and T2 of this circuit can be the BC558. T3 can be a BD135 and T4 a TIP42. The...
This circuit provides an output voltage with the absolute value of the charge and discharge current...
