In this video, I explain the steps that are needed to design a simple shunt regulator circuit using a Zener diode / voltage regulator diode. I provide the basic details for this electronic circuit design for this voltage stabiliser circuit.
This shunt regulator circuit design can be used on its own, or it can be used as the basis of other transistor or FET regulator circuits.
In this video I outline the basic circuit details along with the calculations needed for the resistor, etc in this basic Zener diode regulator or voltage stabiliser circuit. I take a look at the power dissipation levels for the components because it is necessary to ensure that none of the components is over-stressed. Burn-out of the components is certainly not needed!
In the video I state that the max current for the diode should be sufficient to accommodate variations in the load current. For this example it was assumed that the load was unlikely to be completely removed - this can happen in some applications and the maximum Zener current should be the complete current with none passing to the load.
Having designed the basic circuit, I then go on to look at versions of the voltage regulator circuit that can enable higher current levels to be provided using emitter follower transistor circuits. I also detail some important points that need to be noted when designing these transistor circuits.
Please note that at about 3 mins 50, a small error was present where the calculation stated, 0.0179mA, this should have read 0.0179 A = 18 mA. I've tried to blur the m in the 0.1079mA out.
