step up

I'm a beginner electronics enthusiast. I'm working on a variable power supply made from an ATX PSU. For the variable voltage output, I'm planning on using a step up module from the 12V 16A ATX in, boost it up to 30V then connect that to the step down converter for variable voltage. Is this ok...

Hello folks, 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. I have...

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...

Hello, 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...
