Hello, in this video, I wanted to show you how to make a transformerless adjustable power supply. The biggest feature of this circuit is that it uses a transistor to perform the adjustment process and has an AC input and an AC output. This project is made for educational purposes. Please note that there is high voltage on the lines, and do not touch them under any circumstances. Also, if you do not have sufficient knowledge and experience, just watch and do not attempt. The biggest advantage of this project is that it has an AC input and output, as well as using very few components However, please note that the project is dangerous and requires good insulation and cooling for continuous use. Also, the person who makes and uses it is responsible for any problems that may arise.

It is creative, but has some problems: The chosen transistor breakdown voltage (Vceo) goes just to 250 Vdc max. And at 220VAC RMS the peak voltage is up to 308Vdc peak. The Gain/HFE of that same transistor is very low (about 50). For that 70W lamp under 220VAC it needs 320 mA for full brightness. So, current at base Ib= 320/50 = 6 mA. But power dissipation of that 1KΩ and potentiometer of 1MΩ (at 50%) would be 40mW (for R=1K) and 10~20W for the Pot, so the potentiometer may fry or burn 🔥 very easily. Probably using a Darlington stage to drive the transistor would help. As I said, an interesting concept, being surprised that it was not burning, but to make it safe, there still a lot of work to do.

Looks like spikes are present in the supply thats why needed that large heat sink because it is not the correct way to operate a load best you can do to put a triac and diac no need that rectifier also

muy buen video educativo, solo le faltaría saber hasta que amperaje máximo se podría usar, por ejemplo con un motor de un cuarto o mas , es muy importante, ya que la red esta llena de proyectos que solo encienden lamparas o hacen funcionar una amoladora de mano o una agujereadora . no lo tomes como critica, solo analizalo. gracias por tus videos..

@BjornV78
@BjornV78 Год назад
With 240V mains voltage, a 100K potentiometer will burn up in flames. The potentiometer in this circuit is connected in parallel to the full rectified mains voltage, that is arround 166V for 120V mains, and 334V for 240V mains. 334V over a 100K resistor dissipates 1,11Watt, where a normal carbon potentiometer only is rated for 1/4Watt.
