I'm just new to the forum. I'm looking for help using a 400w 15A DC-DC step up boost converter 10-60 volts.
I watch many youtube video of people who can set voltage and amperage with that.
But I can't do the same. Here is my project : I want to power a COB LED 30-34v 200w.
1. I use a medical therapy device that needs 72 volt ac input.
2. Need to drive the medical device from a 5 volt dc Powerbank for mobiles that are readily available in markets
3. For that, I need to somehow step up the powerbank output from 5vdc to 72volt (either ac or dc)
4. The max load...
I am an electronics engineering graduate but with the easy recruitment and stuff I am working as an IT engineer.
I still do have my electronic circuits, microcontroller and sensors for hobby purposes.
Here I have a dream to use thermal energy conversion to mechanical and then...
Had some circuits put together in china and shipped to UK for a project. Long story short the ozone the arc was producing was too much of a concern for the product as it was being inhaled directly.
They produce an arc up to 7 mm across.
Have 500 of these circuits sitting around, does anyone have...
Hey, I have a question regarding a schematic I made, which doesn't work. Maybe someone could help me out. I tried to make a board which would take a 1.5V Battery and turn it into 5V. I used this IC: https://www.mouser.de/datasheet/2/256/MAX8815A-1516131.pdf
I oriented myself with the schematic...
HI all, I want to understand the proper way to make a dimming function for the XL6005.
I found some schemes that suggest using the EN Pin:
And some that use the FB Pin:
So which one should do the work and what PWM signal should I use?
I'm working on designing a circuit with two distinct loads - one being a DC motor and another being an LED strip. I want to run both off the same power source, but they have different voltage requirements. The strip requires a fixed 5V and the motor will require 12V+.
I'm currently planning...
Hi. I am trying to build a power supply which output is 2000VDC and 20mA (40W) input is 220V ac (european input).
I thought I can use flyback transformer. And I started to design. I selected duty cycle as %50 and frequency as 50kHz (actually I don't know how to select frequency and duty cycle...
I have a media cabinet which houses a bunch of media players/routers/alarm system etc.
The target output voltages for each component is between 9V and 24V. This is currently powered by an LED power supply with a few step down buck converters to the target voltages. The LED power supply is very...
