optocoupler

Optokuplör ile role devresi, bir kontrol devresi ile bir yük (load) arasındaki elektriksel bağlantıyı izole etmek için kullanılan bir konsepti ifade eder. Optokuplör, bu izolasyonu sağlamak için kullanılan bir bileşendir. İşte bu konsept hakkında daha fazla detay: 1. **Optokuplör Nedir?**...

The photo-transistor and photo-darlington devices are mainly for use in DC circuits while the photo-SCR and photo-triac allow AC powered circuits to be controlled. There are many other kinds of source-sensor combinations, such as LED-photodiode, LED-LASER, lamp-photoresistor pairs, reflective...

This universal triac controller circuit with optocoupler solves the problem that triacs have when functioning at low temperatures (triac needs higher gate current) by adding a transistor at the output of the optocoupler circuit. The transistor amplifiers the trigger pulse coming from the...

I recently made ​​another switching power supply, this time 14.5V 0.4A. It can be used virtually anywhere. I use it as an auxiliary voltage supply for MOSFET and IGBT halfbridge drivers. The source is very similar to the previous 3.4V 2.5A supply. Therefore, I won't describe the principles of...
