Hi,
I'm new to this forum (and forums in general). I am starting my second year of engineering school (midlife career change) and have a problem I have been trying for figure out, on and off, for about a year. With an unregulated 35VDC input I am wanting to use a MCU (ESP32 specifically) to...
Hi Experts,
I've SMPS (AC to DC) which gives output of 12V, 20A, 240W,
& I've to attach Peltier device (TEC1 12706) with SMPS, but
Confusion is Peltier have max. Current rating as 6A, but SMPS is giving 20A,
So how to limit o/p of SMPS to 6A, so it wont damage Peltier,
how current regulation...
Hello,
I'm looking to design a stupid simple DC-DC converter with two goals only:
Current regulation to no more than 90 amps
Lowest possible cost (total cost sub $50)
Can it be done?
The power supply is a Prius. The Prius Gen 2 DC-DC converter (used instead of an alternator to charge the...
hello everyone, this is a stupid question but if anyone can answer this, i'd be so grateful. the question is about the transformer core. take a simple EI laminated silicone steel core for example. we know primary winding magnetises and secondary demagnetises. and at a some point an equilibrium...
Toshiba is almost %100 efficient, no cooler at 2–2.5A, way ahead than any other thing for such currents. So cheap and as a kit perfect to use daily everywhere by youth. One handy short current topology makes it killer because it is stackable as paralel. You can easily do 100A box without a fan...
I'm posting today hoping for some guidance on a project i would like to attempt. I recently came into a lot of 64 12v 7AH Sealed Lead Acid batteries from a backup UPS. The batteries are still good and take a charge and load like normal for the most part. Since i only have the batteries and...
I am developing a basic switching circuit using a PIC microcontroller where the maximum drive current will be up to 2A in this case I was using BD139 but now due to my PCB has a Single-layer option I have to use SMD for it. so, please anyone suggest to me the best NPN SMD transistor for my...
hi,
i have 4 led lights designed to work in ac but i want to use them in a garage that doesn't have power.
The lights consist of just an led strip without any resistors, have a forward voltage of 60v and draw 300mA.
I thought of removing the ac/dv converter and just use a 60v battery to power...
How can I control the current that is supplied to a battery? I need to balance current consumption to avoid some parts of the system run out of power.
My system is described in the attached file. I have a 12V input which goes into a Boost regulator to get 48V. Those 48V are used to feed a...
