    1000w smps based on LUDO3232

    Is there a thread on this one?

    1000w smps based on LUDO3232

    Hi Silvio! What about that project with EE55? it's finished?

    1000w smps based on LUDO3232

    Hi Silvio! I would like to build this source but with EE55, for sure I will have to remake the pcb to fit my horizontal core with grommet pins that I bought by mistake. Will 0.45mm-0.7mm wires work for me or should I buy a thinner one? Did you short-circuit the output? Greetings! IvanElectric

    The numbers that I marked from 1 to 6, are not corresponding to the IC, but they would be the connection pins of the mini pcb to my main pcb (power)

    What I am saying is that between schematic and pcb (V2) there are inconsistencies. RC 330K ----->PIN#6 (IR2153) in board. No schematic.

    Silvio, good afternoon. I was thinking of redesigning the mini IC PCB so I can keep my power PCB. So I have the following question: The RC-CC set on the V2 smps takes from the center of C6-C7, but your mini oscillator PCB has that RC-CC set connected to pin # 6 of the IC. Is the same??? Is it...

    I will be trying different things for the protection that I have at the moment. But I'll be waiting for the CT80 to be published sometime, at the moment I only have 0.45mm / 0.7mm / 1mm wires. I really liked this compact source with EE42 I got 800W continuous and it has 12V outputs for coolers...

    You uploaded another PCB V2 file, which has Soft-Starter + S / C with SCR. Is that functional? The CT 80: 1.5 how did it?

    I am looking at circuits on the web to know that I can change or redo that stage

    I have also changed the value of C from 100nF to 1uF, in addition to the R that he had told me of 2K2. Unfortunately, the source still does not reset by itself, nor by disconnecting from the electrical network.

    I changed the R from 4k7 to one of 2k2 (C is still 100nF) the protection once activated does not not even if you turn off the power supply and reconnect it

    I have 150K resistors to discharge C6 and C7. I have lowered the value of the R of 4K7 associated to the Vr1 (for one of 3K) without obtaining different results, I replaced 4K7. I will change those two values that you just indicated and notice that it happens. PS: my Vr1 is 5K (is there a...

    Audio smps 700w (IR2153)

    I have put the setting to the minimum, I do not think that the soft start will solve it since when the source is protected by protection, for some reason and no matter how much capacitors are discharged, it starts again protected. However, if I make a bridge between the base and emitter of...

    The PCB that I show below is based on your schematic (I saw it on PCBshare) but looking deeper is that I came to this forum and found that it was originally from you. My smps has 940uF / 100V per rail (2 * 470uF in parallel). Protection is SCHMITT TRIGGER. Momentarily I removed the coil that...

    Audio smps 700w (IR2153)

    I have downloaded C5, C6, C7, etc, etc and when I turn on the source it starts protected. The only way it is unprotected is by moving the adjustment preset or by bridging the base and emitter of the 5551.
