SCR Applications Circuits
In this article I have explained many interesting SCR application circuits and also learn the main features and properties of an SCR also called a thyristor device. What’s an SCR or Thyristor SCR is the acronym of Silicon Controlled Rectifier, as the name suggests it’s a kind of diode or a rectifying agent whose conduction […]
High Voltage Constant Current Source Circuit
The presented circuit offers an adjustable constant current source capable of reaching up to 60mA, operating at voltages as high as 350V. Circuit Description The input stage, consisting of resistor R1 and zener diode ZD1, delivers 8V to the regulator (a 7805), maintaining this voltage relative to its reference line. This voltage level ensures sufficient […]
