The problem isn't making 5V voltage. The problem is how to connect this offset to op-amp inputs to work fine.
Look on picture below:
I want to make regulation:
IN:10V --> OUT: -10+5=-5
IN: 5V --> OUT: -5+5=0
IN:0V --> OUT: 0+5=5
I connected 5V to input "1" and "5". I giving on input 10V and...
Hello,
I would like to make voltage regulator using op-amp. I want to give 0-10V on input and get -5V to 5V on output.
I made inverting amplifier with ku=-1. My problem is that I need to add offset 5V to amp, but I don't know how to do it.
Schematic is below:
I know, that I need to use input...
I have 3-phase wind-turbine 20kW with inverter connected to my home electric instalation. I installed it to heat water in a boiler, like in schematic below:
Heater in boiler is also 20kW.
But now I have a problem: when there is weak wind and low wind-turbine energy production, most energy is...
In my transformer I need about 2mm^2 for primary and 3mm^2 for secondary wire diameter. I deduce that I won't get 26A with freuency 150kHz, because wire will be too thick as you said.
Is it better idea to put:
PRIMARY: 34 turns / 1mm^2 diameter
SECINDARY: 6 turns / 1,5mm^2 diameter
That's what...
I have calculated windings and the results are as follows:
PRIMARY: 17
SECONDARY: 3
TURNS RATIO: 5,667
Bmax: 1350G
I have a question about windings. Is it allowed to multiply it, for example 2x (prim 34, sec 6)?
I still don't know any relationship between wire diameter and frequency
Hello, I want to design and wind transformer to smps with parameters:
INPUT: 160V / 4A
OUTPUT: 24 / 26,667A
POWER: 640W (this power is needed to start motor, constant power needed is 170W)
FREQ: 150kHz
I have disassembled PC power supply ATX 300W and get core EI-33C form it, like on screen...
Hi,
I want to build small buck converter wih parameters:
input: 36V DC
output: 30V DC
power: 60W
Someone know any existing schematics, which could help me?
Hello all,
At the beginning I want to say, that i didn't make smps before. I wish to construct power supply with following parameters: 24V 10A 240W (around), powered form the mains. The smps will be used to power 24V DC motor. I checked out some forums but couldn't find any scheme. Can someone...
