@@808pathfinder Yeah I noticed how fast it heats up if the load draws a lot of current even with a heatseek. Maybe a resistor on the output would help regulate the current draw.
@@tetraederzufrequenztesla2342 that's a good idea. The lm317 is a voltage regulator that limits the current draw as well I believe. That should stop the mosfet or transistor from overheating.
Muito bom projeto com ajuste de tensão de saída. gostaria de saber se não precisa usar um dissipador de calor no transistor? Valeu pelo video, Deus abençoa.
While it makes a good variable output voltage source, as a regulator not so much. If the load changes, the voltage will need adjusted to compensate. So variable output, yes, regulator, no! However nice simple setup. Thumbs Up!
The circuit is a simple "source follower" setup where the voltage at the source follows the voltage set by the potentiometer. This leads to three problems, one minor and two major. The minor problem is that the output voltage changes with the load current, but not by much. The output impedance is the reciprocal of the forward transconductance (minimum of 19 S from the data sheet), so the output voltage will drop by about 0.05 volts per amp. The first major problem is that the output voltage changes *directly* with any change in input voltage, so there is no regulation as such, and no ripple or noise rejection. The other major problem is that without a heatsink, the IRFZ44N has a temperature rise of up to 62 C per watt. A circuit similar to one demonstrated used to drive a 12V LED from 29V supply would drop (29-12) = 17 volts across the MOSFET. If 1 amp of current were provided, it would produce (17 x 1) = 17 watts in the transistor, potentially raising its junction temperature by as much as (62 x 17) = 1,054 degrees Celsius. These MOSFETs were designed for switching operations where they are either fully on or fully off. Using them in linear applications requires a sizeable heatsink.
IRF540 VR 50k Diye 12v motor control korar jonno... But MOSFET khub e gorom Hoi. 1 min calanur por ar hat laganu jaina ... Emn holo kno plz bolben ...!
Many wonder how many amperes you can absorb, if as in the video you provide an input of 24V and an 12V output load, without the heatsink, you can deliver 0.167 amperes, because this transistor can dissipate only 2 Watts.
please, can you help me? I wanted to create a circuit that would plug into 110v or 220v and give a 12v output with 7a to continuously power a screwdriver that blew the battery. Would you have any examples ??? thanks and i'm a fan of your channel, congratulations.
For me the best solution is to buy a switching power supply. But if u want create a circuit at home, the easiest way is a linear psu. Transformer, full bridge rectifier, capacitor and a Lm7812. But this ic can output max 1amp. U have to add an external power transistor to amplify the current capability on this circuito.
Perdon por la ignorancia. ..necesito hacer un. Circuito para un generador dc 24 volts. Yo lo puedor rectificar a mi gusto. Y agregarle el regulador ok. Busco algo para usarlo cinco o seis horas. Si me ayudaras. Dandome un tip. Gracias x tu tiempo
Nice idea im going to make it.i have a epson dc motor its 12 to 42 volts. I test my dc power supply to a epson dc motor, around 19 volts the motor will start to spin faster.my favorite part is i like when the motor start spinning in reverse at 19 volts or greater with the blade attached to it while spinning And i see sparks when i be in the dark lol.
Muy buen video ise uno con resistencia y vultimetro y le puse como 27v y se kemo el vultimetro la verdad creo k sólo 12 bol aguantaba por k con una batería d 12 voltio si funcionó probaré este a ver k tal
Amigo puedo ponerle un par de rectificadores de 3 Amper en paralelo y k lleve un filtro de 2200 a 25 v para amortiguar la entrada de ,24 vcd de la batería me pueden informar si sirbe
