Sir, your way of explaining is having fully touch of an Engineer. You explain the things with theory and problem calculation and with reasoning which helps to understand the subject without any doubt. Thanks for your nice explanation.

Well, the maximum input voltage of the 7805 is specified to 35 V. You operate the device across its break-though voltage, which is obviously around 46V. Only the input capacitor and the internal break through resistance of the 7805 limits the undefined current (here considerably smaller than 12 mA) across the device. I am surprized that the 7805 is still working if it's break-through voltage is exceeded. Nevertheless, this operation can harm the 7804 after a certain time and there will be no more 5V limiting behaviour after a while and the diode can be damaged too. My suggestion is to eliminate the 7804 and to use a 5 V zener diode behind the smoothing capacitor to get always a well defined voltage across the LED and its resistor. It will also draw down the rectified voltage to well defined 5 V. So you can use a smaller electrolytic capacitor with a voltage rating of 10 V (how did you decide your voltage rating or did you use a 400 V specified device). The current across the zener diode and the LED is well defined. Even when the LED gets disconnected, the circuit will not fail.

Zener diodes dissipate power all the time. I prefer using regular ics but the input side must be protected with higher voltage zener diode (close to 35v) . At higher voltage, zener diode's power dissipation should be lower.

@gkdresden

@@user-vo6yr8rf4c no, the power dissipation of a Zener diode at a higher voltage is higher. In fact, at voltages higher than 8 V Zener diodes doesn't work with the Zener effect but with avalanche breakdown. Considering the data sheet for the BZX55-series in all cases you need to set the operating current for the Zener diode to at least to 5 mA. So for 5.1 V you only dissipate 25 mW. At 30 V you dissipate 150 mW. Furthermore you dissipate power in the linear regulator. For 12 mA and a voltage drop from 30 V to 5 V you dissipate 300 mW. So in total you dissipate 450 mW. This is much more than 25 mW. The most important rule for a capacitor voltage supply is to develop the active power at the lowest useful voltage. Otherwise you not only increase the power dissipation but also the reactive power at voltages considerably lower than the mains voltage. The reactive power for the zener diode regulator is 2 W. The your solution it is 40 W!

Hi. I think you have made a mistake in your circuit. You calculated the circuit for 12mA. But you have a voltage drop of 15V above the 220 Ohm resistor. That means a total current of 68mA. The calculation for the voltage drop capacitor is wrong. 1 ------------------------------- = 125nF not 1.25 µF 2x3.14 x 50 x 25333 I think the voltage regulator is close to end in a gammaburst ;-) Nearly 50 Volts is very much for a 7805. That could be the reason therefore that the output voltage is only 4.8 Volts. The regulator is running critical. Normaly the output voltage of a 7805 is very close to 5 Volts. But regardless of that it is a nice video. Thanks.
