Hi bro, this is probably one of the cleanest projects around, good job! May i know what is the max current on input? I am looking for something to use with an old server psu @12v 2500w approx 200amps. your suggestion would greatly be appreciated.

[@wirebrushproductions1001]

Congratulations - by mounting your MOSFETs on top of the ring mounts, and not using any heatsink compound, you've reduced the power-handling abilities of the MOSFETs by about 60 to 70%. And if you use a power supply of more than about 20 volts, it will be possible to destroy the MOSFETs if you turn the pot all the way up. If you attempt to use this setup for higher currents, you will probably overheat the transistors if you try to put out high currents at low voltages with a high input voltage. Your heatsink is entirely inadequate for the voltages and currents which you claim will work.

[@homemade_101]

thank your advice.

[@readytorvdude1224]

Are those eye ring terms for external positive battery inputs??? Seems very likely & reasonably sound schematic, 'cept the over heating / not adequate for high current issues??? Can you elaborate on a high current build for say 12v-24vdc input TO 48v-120vdc high current 50a output

[@wirebrushproductions1001]

@@readytorvdude1224 You cannot possibly get more voltage out than you put in. And if you somehow have 24 Vdc in and 120Vdc/50 A out, you'll need 250 amps in. I cannot "elaborate" on a fantasy. Even something like 24 volts in/12 volts out @50 amps cannot work with those puny wires.

[@readytorvdude1224]

@@wirebrushproductions1001 thanks for replying. I'm trying to harness the alternator B+ amperage out (2ga awg) into DC/DC boost converters; (12v/150A output thru the boost modules (2 in parallel) to convert into 24v or 36v(30A 1500W max) outputs into a MPPT solar charge controller at PV INPUT. Is this practical??? Wouldn't the lower voltage at PV INPUT ALLOW FOR HIGHER AMP INPUT THERE?

[@wirebrushproductions1001]

@@readytorvdude1224 "Is this practical?" No. Not only no, but Hell no. The wiring shown is completely inadequate to handle the currents you are trying for. But hey, don't listen to some stranger on the internet who hasn't made a video. The parts are cheap. Build one channel and give it a try. Watch it burn up with your own eyes. Did you know that transistors actually run on magic? It's a trade secret that at the center of each package is a pocket of Magic Smoke, which actually makes the transistor work. The proof of this is the fact that if you let the Magic Smoke out, the part will stop working. Build your own copy of this circuit and prove it for yourself.

Doesn’t the diode prevent the Rgs pull-down resistor from functioning? The Rgs resistor is meant to connect Gate to Ground, but in this case the diode is blocking the ‘gate capacitor’ drain. Theoretically, the potentiometer is acting as Rgs anyway (depending on its position) but it’s not a reliable pull-down resistor due to its variable nature. I assume that’s why the other resistor was added, however the diode appears to make it redundant?

[@homemade_101]

Yes, It is no need. but it has used an motor back emf blocker.

Try this one : kzbin.info/www/bejne/eXyTfouvr7h4htEsi=gGxJLo9Md1MJHbgz

[@davidjackson2115]

could it be the motor turning off on with the commutaion which means the mosfets gates are getting turned off and on fast thus will be cooler. While the straight out resistance load of the bulbs will mean the mos gates are on boarder line off / on which is what generates the heat. Good if you can introduce a pulsed circuit with input caps to store the incoming power when pulsing mosfet is off {to use that solar power moment the mosfet is switched on} and have that above circuit using only one mosfet to control gate threshold trigger voltage of pulsed mosfet. But what do I know, Im here because I blow mosfets and need a decent regulator. Like the joker says "If you want anything done properly - youve got to do it yourself"

[@davidjackson2115]
